The first weeks after surgery: what happens in the hospital and at home

You will spend one to three days in the hospital after shoulder replacement surgery. During that time, nurses will manage your pain with medication, monitor your incision for signs of infection, and begin gentle movement exercises with a physical therapist. Before you leave, you will receive written instructions on wound care, medication schedules, and which movements to avoid. Most people go home with their arm in a sling and a prescription for pain medication.

The first two weeks at home are the most restricted. Your incision will be tender and may have small amounts of drainage—this is normal. You will need to keep the area clean and dry, change the dressing as instructed, and watch for signs of infection like increasing redness, warmth, swelling, or pus. Pain is usually worst in the first week and gradually improves. Many people find that ice packs (wrapped in a towel, never directly on skin) and elevation help with swelling.

You will not be able to drive while taking prescription pain medication or while your arm is immobilized. Arrange for someone to help with household tasks, cooking, and personal care for at least the first two weeks. Your surgeon will schedule a follow-up visit around two weeks after surgery to check your incision and clear you for the next phase of recovery.

Key Takeaways

  • Hospital stay is typically one to three days, and you will go home with your arm in a sling and pain medication.
  • The first two weeks require careful wound care, ice and elevation to manage swelling, and help from someone at home for daily tasks.
  • Physical therapy begins in the hospital and continues at home or in a clinic, starting with passive motion and progressing to active exercises over weeks and months.
  • Most people regain basic shoulder function within three to six months, but full strength and range of motion can take nine to twelve months.
  • Infection, stiffness, and persistent pain are the most common complications, and your surgeon should evaluate any sudden changes in swelling, warmth, or fever.

Physical therapy: the timeline from passive to active movement

Physical therapy is the core of your recovery. It begins in the hospital with a therapist moving your arm gently for you—this is called passive range of motion. Your job is to relax and let the therapist move your shoulder. This prevents stiffness and keeps the joint mobile while your muscles are still healing.

Around week two or three, you will transition to active-assisted range of motion, where you do some of the work with the therapist's help. By week four to six, you will begin active range of motion exercises—moving your arm yourself without information. These early exercises are small and controlled: pendulum swings, gentle lifts, and supported reaches. Pain should not be sharp; a mild ache is normal.

Starting around week six to eight, your therapist will add light resistance exercises using bands or light weights. By three months, most people can perform everyday tasks like reaching for objects at shoulder height, combing their hair, and dressing themselves. Strengthening continues through month six and beyond, with heavier resistance and more complex movements.

You will typically attend physical therapy two to three times per week for eight to twelve weeks, then transition to home exercises. Your therapist will give you a written program to follow at home. Skipping sessions or not doing home exercises significantly slows recovery, so consistency matters more than intensity.

Pain, swelling, and what is normal versus what needs attention

Pain after shoulder replacement follows a predictable pattern. It is usually worst in the first week, improves noticeably by week two, and continues to decrease over the first three months. Most people need prescription pain medication for two to four weeks, then switch to over-the-counter options like acetaminophen or ibuprofen as needed. Some discomfort during physical therapy exercises is expected—your therapist should help you find the line between therapeutic challenge and harmful pain.

Swelling peaks around day three to five after surgery and gradually subsides over two to three weeks. Ice, elevation, and compression (if your surgeon recommends it) all help. Some swelling may return after physical therapy sessions, especially early on. This is normal and usually resolves within a few hours.

Contact your surgeon when ready if you experience fever above 101°F, increasing redness or warmth around the incision, pus or foul-smelling drainage, sudden increase in swelling, severe pain that does not respond to medication, or numbness and tingling in your arm or hand. These can signal infection, blood clots, or nerve involvement—all require prompt evaluation. Do not wait for a scheduled appointment if you notice these signs.

Returning to daily activities and work

Most people can return to light desk work or sedentary jobs within two to four weeks, depending on pain levels and how quickly swelling decreases. If your job involves physical labor, lifting, or repetitive arm use, recovery takes longer—typically six to twelve weeks before you can return full-duty, and sometimes longer.

Household activities return gradually. By week three to four, you can usually manage light cooking, eating, and personal hygiene with your affected arm. Driving is safe once you have stopped taking prescription pain medication and can move your arm enough to steer and control the wheel—usually around week four to six, but check with your surgeon first. Heavy lifting (anything over 5 to 10 pounds) is restricted for at least three months, sometimes longer.

Recreational activities depend on the activity. Walking and stationary cycling can resume around week four to six. Swimming and water therapy often start around week six to eight once the incision is fully healed. Contact sports, throwing, and overhead activities like tennis or baseball typically require four to six months of recovery before your surgeon clears you to return.

Stiffness and loss of motion: why it happens and how to prevent it

Frozen shoulder (also called adhesive capsulitis) is the most common complication after shoulder replacement. It occurs when scar tissue builds up inside the shoulder joint, restricting motion. It is more likely if you skip physical therapy, avoid movement due to fear of pain, or have diabetes or other inflammatory conditions. The risk is highest between weeks two and twelve.

Prevention is much easier than treatment. Consistent physical therapy, doing your home exercises even when they feel uncomfortable, and gradually pushing your range of motion within safe limits all reduce the risk. Your therapist will help you distinguish between the discomfort of working through stiffness and the sharp pain that signals you should stop.

If stiffness develops despite your efforts, your surgeon may recommend more intensive physical therapy, manipulation under anesthesia (where the surgeon gently moves your shoulder while you are asleep to break up scar tissue), or both. This is why early, consistent therapy is so important—it is far easier to maintain motion than to regain it after stiffness sets in.

Strength recovery and realistic timelines for full function

Strength returns slowly and unevenly. At three months, most people have regained enough strength for everyday tasks but tire easily with repetitive use. At six months, strength is noticeably better, and most people can do light recreational activities. Full strength—comparable to your pre-injury shoulder—typically takes nine to twelve months, sometimes longer.

The timeline depends on your age, overall fitness before surgery, how consistently you do physical therapy, and the specific reason you needed the replacement. Someone who had a rotator cuff tear along with arthritis may recover more slowly than someone with arthritis alone. Your surgeon and therapist can give you a more specific estimate based on your situation.

Patience is essential. Many people feel frustrated around month three or four when progress slows. This is normal. Strength gains continue through month twelve and beyond, even if they are not as obvious as they were in the first few weeks. Continuing your home exercise program, even after formal physical therapy ends, makes a real difference in your final outcome.

Sleep, medication, and managing discomfort at home

Sleep is often difficult in the first few weeks because lying flat puts pressure on your shoulder. Most people sleep better propped up with pillows or in a recliner. Placing a pillow under your upper arm and elbow takes pressure off the joint. Pain medication taken 30 minutes before bed can help you fall asleep more easily.

Your surgeon will prescribe pain medication—usually an opioid for the first week or two, then transition to over-the-counter options. Take medication on a schedule rather than waiting until pain is severe; staying ahead of pain is easier than catching up. If you are sensitive to opioids or prefer to avoid them, talk to your surgeon about alternatives like nerve blocks or other pain management strategies before surgery.

Ice is your friend in the first four to six weeks. explore ice for 15 to 20 minutes at a time, several times per day, especially after physical therapy. Wrap ice in a towel—never explore directly to skin. Heat can be helpful later in recovery (usually after week four) to relax muscles before exercises, but ice is better for managing swelling early on.

When to contact your surgeon and red flags you should not ignore

Beyond the infection signs mentioned earlier, contact your surgeon if you experience sudden loss of motion (especially if it happens over a few days), severe pain that is getting worse rather than better after the first week, signs of blood clots like calf swelling or warmth in your leg, or any concerns about your incision that do not match what you were told to expect.

Also reach out if your physical therapy is causing sharp, shooting pain rather than mild discomfort, or if you feel like your shoulder is slipping or unstable. These are not emergencies, but they need evaluation. Your surgeon has seen hundreds of recoveries and can tell you whether what you are experiencing is normal variation or something that needs adjustment.

Do not hesitate to ask your surgeon or therapist questions about your specific recovery. Recovery from shoulder replacement is a partnership between you, your surgeon, and your physical therapist. The more you understand what to expect and why, the better you can manage your recovery and catch problems early.

Frequently Asked Questions

How long before I can sleep normally on my shoulder again?

Most people can return to sleeping on their side around three to four months, once the incision is fully healed and pain has decreased significantly. Your surgeon will give you the all-clear based on your individual healing. Until then, sleeping propped up or in a recliner is safer and more comfortable.

Will I ever have full range of motion again?

Most people regain 80 to 90 percent of their pre-injury range of motion within a year. A small percentage experience some permanent limitation, usually in overhead reaching. This depends on the type of replacement, your age, and how well you do physical therapy. Your surgeon can discuss realistic expectations for your specific situation.

What if I fall on my shoulder after surgery?

Contact your surgeon when ready, even if there is no obvious injury. A fall can damage the replacement or the surrounding tissues. Your surgeon may want imaging to check for damage. Do not assume you are fine just because you do not have severe pain—some injuries do not hurt right away.

Can I shower or bathe with my incision?

Your surgeon will tell you when it is safe, usually around two weeks once the incision has closed. Until then, keep the incision dry. After clearance, you can shower normally but avoid soaking in a bathtub or swimming until your surgeon says it is safe, usually around six to eight weeks.

Do I need to wear the sling forever?

No. Most people stop wearing the sling around week three to four as pain decreases and motion improves. Your physical therapist will tell you when it is safe to stop. Wearing it longer than needed can actually slow recovery by preventing you from using your arm, so follow your therapist's guidance on weaning off it.
