Hip replacement surgery itself is not painful because you are under anesthesia

During the operation, you will be asleep or sedated—you will not feel pain while the surgeon removes the damaged hip joint and implants the artificial one. The pain comes after you wake up, when the anesthesia wears off and your body begins healing from the incision and the work done inside your hip joint.

Most people describe post-surgery pain as moderate to severe in the first few days, then gradually improving over weeks and months. The intensity depends on your pain tolerance, the surgical approach your surgeon used, how well you follow physical therapy, and whether you take pain medication as prescribed. Pain is not a sign something went wrong—it is a normal part of healing.

Key Takeaways

  • Pain peaks in the first 24 to 48 hours after surgery and is typically managed with prescription opioid medication, which you can adjust with your doctor's guidance.
  • Most people move from strong pain medication to over-the-counter options within two to four weeks as the incision heals.
  • Physical therapy causes temporary soreness because you are moving a joint that wants to stay still, but this movement is essential to prevent stiffness and improve long-term function.
  • Pain that worsens after improving, or pain accompanied by fever, swelling, or redness around the incision, should be reported to your surgeon when ready.

Pain in the first week after surgery

The first 24 to 48 hours are typically the most painful. Your hip has a fresh surgical incision (usually 8 to 10 inches long), the joint has been dislocated and repositioned, and swelling is at its peak. You will likely be in a hospital bed or recovery facility where nurses can monitor your pain and adjust medication.

Your surgeon will prescribe strong pain medication—usually an opioid like oxycodone or morphine—which you take on a schedule, not just when pain breaks through. Taking it regularly keeps pain from building up rather than chasing pain after it arrives. Most people need these medications for the first one to two weeks. By day three or four, many people report pain dropping noticeably as swelling begins to decrease.

You will also receive ice packs, compression wraps, and elevation to reduce swelling, all of which reduce pain. Some surgeons use nerve blocks—injections that numb the surgical area for 12 to 24 hours after surgery—which significantly lower pain in those critical first hours.

Pain during physical therapy and movement

Physical therapy begins within hours or days of surgery, while you are still in significant pain. A therapist will have you bend and straighten your hip, walk with a walker or crutches, and perform exercises that feel uncomfortable. This is intentional and necessary—your hip joint will stiffen if you do not move it, and stiffness is harder to reverse than the temporary soreness of therapy.

Therapy pain is different from surgical pain. It is usually a sharp, localized ache in the hip joint itself rather than the duller, broader pain from the incision and swelling. It typically fades within an hour of stopping the exercise. Taking pain medication 30 to 45 minutes before therapy makes movement easier and helps you do the exercises more fully, which speeds recovery.

Most people find therapy pain decreases week by week as the joint becomes more mobile and muscles strengthen. By four to six weeks, many people report that therapy soreness is mild and manageable without strong medication.

Pain from the surgical incision

The incision itself causes a different type of pain than the joint pain—a burning or tender sensation along the cut, especially when you move in ways that stretch the skin or put pressure on the area. This pain is usually worst in the first two weeks and improves as the incision closes and the scar begins to mature.

Swelling around the incision peaks around day three and then gradually decreases. As swelling goes down, incision pain typically drops significantly. You can manage this pain with ice (15 to 20 minutes at a time, several times a day), keeping the leg elevated, and avoiding positions that pull on the incision.

By six weeks, most people report that incision pain is minimal—a mild tenderness rather than sharp pain. The scar will remain sensitive for several months, but the acute pain phase is usually over by then.

Pain weeks two through six

By the end of week two, many people transition from prescription opioids to over-the-counter pain relievers like acetaminophen or ibuprofen, though some people need opioids longer depending on their pain level and how quickly they are progressing in therapy. Pain at this stage is usually moderate—noticeable but not disabling, and manageable without strong medication for many people.

Weeks three through six are when most people notice steady improvement. Pain continues to decrease, swelling continues to reduce, and your range of motion improves. You will likely still have soreness after therapy sessions and at the end of the day, but mornings often feel better than evenings as swelling builds throughout the day.

By six weeks, many people report pain only during or when ready after physical therapy, or at the end of a day when they have been active. Pain at rest is usually minimal. However, pain timelines vary widely—some people heal faster, and some need more time.

Pain beyond six weeks

After six weeks, most people are off prescription pain medication entirely. Residual soreness is common—a mild ache in the hip, especially after activity or at the end of the day. This is normal and typically continues to improve through three to six months as the hip continues to heal and strengthen.

Some people experience a dull ache or stiffness in the morning that improves with movement and heat. Others feel occasional sharp twinges when they move in certain ways. These sensations usually fade as scar tissue matures and the hip becomes stronger.

If pain worsens after improving, or if you develop new pain that is severe or accompanied by swelling, redness, warmth, or fever, contact your surgeon. These can be signs of infection or other complications that need attention.

Managing pain at home

Pain management at home relies on medication, ice, elevation, and activity. Take pain medication on schedule in the first weeks rather than waiting until pain is severe—this keeps pain from building and usually requires less total medication. As you improve, you can space doses further apart or switch to milder options.

Ice reduces swelling and numbs pain. Use it for 15 to 20 minutes at a time, several times a day, especially after therapy or activity. Elevation above heart level also reduces swelling. Keeping your leg elevated while sitting or lying down, especially in the first few weeks, noticeably decreases pain and speeds healing.

Heat can help with stiffness and soreness after the first week or two, once acute swelling has decreased. A heating pad for 15 to 20 minutes before therapy can make movement easier. Ask your physical therapist when it is safe to switch from ice to heat—this varies by surgeon and individual healing.

Activity matters too. Staying as active as your surgeon and therapist recommend—walking, doing prescribed exercises—actually reduces pain long-term by preventing stiffness and strengthening the hip. Resting too much often leads to more pain and slower recovery.

Frequently Asked Questions

Will I need opioid pain medication after hip replacement?

Most people take opioids for one to four weeks after surgery, with the highest doses in the first week. Some people need them longer, and some transition to over-the-counter medication sooner. Your surgeon will prescribe what you need and adjust based on your pain level and progress. Taking medication as prescribed, rather than waiting until pain is severe, usually means you need less total medication.

Is pain during physical therapy a sign something is wrong?

No. Physical therapy causes temporary soreness because you are moving a joint that has been immobilized and is healing. This soreness is expected and necessary—moving the joint prevents stiffness, which would cause more pain and disability long-term. If pain during therapy is severe or sharp in a way that feels different from normal therapy soreness, tell your therapist, but mild to moderate discomfort is normal and expected.

When should I call my surgeon about pain?

Contact your surgeon if pain worsens after improving, if pain is accompanied by fever, swelling, redness, or warmth around the incision, if you develop sudden severe pain in a new location, or if you have calf pain or swelling (which can indicate a blood clot). Pain that is steady and improving, even if it is significant, is normal healing. Pain that changes or worsens is worth reporting.

How long does it take to stop needing pain medication?

Most people stop taking prescription pain medication within two to six weeks. Over-the-counter pain relievers may help with soreness for several more weeks. Residual mild soreness or stiffness can continue for three to six months as the hip fully heals, but this usually does not require medication and improves with activity and time.

Can I use ice and heat at the same time?

No. Ice reduces swelling and is most helpful in the first two to three weeks. Heat helps with stiffness and soreness and is usually safe after the acute swelling phase. Ask your surgeon when to transition from ice to heat—this timing varies. Using them at different times of day is fine, but do not alternate them in the same session.
