Normal pain after hip replacement lasts four to six weeks and feels like a deep ache or soreness around the incision and inside the joint

Pain in the first few weeks is expected. Your surgeon cut through muscle, bone, and soft tissue to reach your hip joint and place the new implant. That damage causes inflammation, swelling, and soreness that gradually decreases as your body heals. Most people describe it as a dull, constant ache rather than sharp pain, and it improves noticeably each week if you follow your physical therapy routine and take pain medication as prescribed.

The pain typically peaks in the first three to five days after surgery, then begins to decline. By week two, many people report they need less medication. By week four to six, the acute soreness has usually faded enough that over-the-counter pain relief becomes sufficient. Some tenderness and mild discomfort can persist for several months, especially when you push yourself too hard or try a new movement, but this is different from the sharp or severe pain that signals a problem.

Key Takeaways

  • Normal post-surgery pain is a deep ache that improves each week and responds to the pain medication your surgeon prescribed.
  • Sharp, sudden pain, severe swelling that does not improve with ice and elevation, or warmth and redness around the incision are warning signs that require when ready contact with your surgeon.
  • Pain that wakes you from sleep or prevents you from doing basic physical therapy exercises may mean your medication dose needs adjustment.
  • Pushing through pain during physical therapy is expected, but pain that lasts hours after therapy or prevents you from walking the next day suggests you did too much.

Sharp or sudden pain is not normal and needs when ready attention

If you feel a sharp, stabbing pain in your hip or thigh that comes on suddenly, or if pain that was improving suddenly gets much worse, contact your surgeon the same day. This can signal a dislocation of the new hip joint, a blood clot, or damage to a nerve or blood vessel. Do not wait to see if it improves on its own.

Severe pain that does not respond to your prescribed medication is also a red flag. If you are taking your pain pills on schedule and the pain is still 8 or higher on a 0-to-10 scale, call your surgeon's office. They may need to adjust your dose, check for infection, or rule out other complications.

Swelling, warmth, and redness that do not improve are signs of infection

Some swelling around the incision and throughout your leg is normal for the first two to three weeks. Ice, elevation, and compression help reduce it. But if the swelling gets worse instead of better, or if it is only on one side of your body and your other leg is not swollen, that is worth reporting.

Warmth, redness, or drainage from the incision site are not normal at any point after surgery. If you notice the skin around your incision feels hot to the touch, looks red or inflamed, or has any discharge (clear, cloudy, or bloody), contact your surgeon when ready. These are signs of infection, which requires treatment.

Fever above 101 degrees Fahrenheit in the first two weeks after surgery also warrants a call. A low-grade fever can be normal as your body heals, but anything higher suggests infection.

Pain that prevents sleep or stops you from doing physical therapy may need medication adjustment

If pain is waking you up at night or is so severe that you cannot do the exercises your physical therapist assigned, your current pain management plan is not working. This does not mean something is wrong with your surgery — it means your medication dose or timing needs adjustment. Call your surgeon or the surgical team and describe what is happening. They can change when you take your medication, increase the dose, or add a different type of pain relief.

Physical therapy is essential to recovery, and some discomfort during exercises is expected. But if pain is so bad that you cannot complete your exercises, or if pain lasts for hours after therapy and prevents you from doing them the next day, you are pushing too hard. Tell your physical therapist what happened so they can adjust the intensity, and contact your surgeon if the pain does not settle down within a few hours of rest and ice.

Thigh pain and numbness are common but should improve over weeks

Many people feel pain or numbness on the outside of the thigh, especially if the surgeon used an anterior (front) approach to reach the hip. This happens because nerves in that area are stretched or irritated during surgery. The sensation usually improves over four to eight weeks as the nerves recover, though some people notice mild numbness for several months.

If the numbness or pain is getting worse instead of better after the first month, or if it spreads to other parts of your leg, mention it at your follow-up appointment. Most of the time it resolves on its own, but your surgeon should know the pattern.

Pain that comes and goes as you heal is normal; constant severe pain is not

Your pain will not be a straight line down. Some days will feel better than others, especially depending on how much activity you did the day before. If you walked too much or skipped ice and elevation, pain may flare up. This is normal and usually settles within a few hours of rest and ice. The overall trend should be improvement week to week, even if individual days vary.

Constant, unrelenting severe pain that does not improve with rest, ice, elevation, and medication is not part of normal healing. Neither is pain that suddenly returns after improving for a week or two. Both of these patterns warrant a call to your surgeon to rule out complications like infection, blood clots, or implant problems.

When to contact your surgeon when ready

Call your surgeon's office right away or go to the emergency room if you experience sudden severe pain, chest pain or shortness of breath (signs of a blood clot), inability to move your leg, loss of sensation in your leg or foot, or signs of infection such as fever, warmth, redness, or drainage from the incision. You should also contact your surgeon if pain is preventing you from doing physical therapy or sleeping, even if it does not feel like an emergency.

Your surgeon has seen hundreds of hip replacements heal. They know what normal looks like and what does not. If you are unsure whether your pain is expected, it is always better to call and describe what you are experiencing than to worry in silence.

Frequently Asked Questions

How much pain is normal right after surgery?

Significant pain in the first 24 to 48 hours is expected — you have just had major surgery. Most people rate it 6 to 8 out of 10 even with pain medication. This should decrease noticeably by day three to five. If pain is not improving by day five despite taking medication as prescribed, contact your surgeon.

Can I take over-the-counter pain medicine instead of prescription pain pills?

Not in the first week or two. Your surgeon prescribed stronger medication because the pain is too severe for over-the-counter options. After four to six weeks, as pain decreases, you can usually switch to ibuprofen or acetaminophen. Ask your surgeon when it is safe to make that switch and whether there are any restrictions on which over-the-counter medicines you can use.

Is it normal to have pain months after hip replacement?

Mild discomfort and occasional aches are common for three to six months as your body continues to adjust to the new joint. Sharp pain, severe pain, or pain that is getting worse rather than better months after surgery is not normal and should be reported to your surgeon.

What does a blood clot feel like after hip replacement?

A blood clot in the leg usually causes sudden severe pain, swelling that is much worse on one side, warmth, and sometimes redness or a cord-like vein you can feel. If you experience these symptoms, especially with chest pain or shortness of breath, go to the emergency room when ready.

Should I push through pain during physical therapy?

Some discomfort during exercises is expected and normal. But sharp pain, pain that lasts for hours after therapy, or pain that prevents you from doing exercises the next day means you did too much. Tell your physical therapist so they can reduce the intensity. Pain should feel like a stretch or mild ache, not like you are damaging something.
