<s>[INST] I fell very hard on my thigh on the right side while biking ( I should mention that even though I m 38, (5 5 and 135 lbs) I ve had several right hip replacement surgeries). The muscle was sore and badly bruised and I could hardly walk for a few days. I can now walk fine but it has been about three weeks and it is still bruised and very itchy and I m not anywhere else, is that normal?or should I see a doctor. [/INST] Hi, Bruise is the collection of blood underneath your skin, occurring due to rupture of small sub-cuticle blood vessels, usually bruise takes 4-6 weeks to disappear, sometimes even longer then that. So for a bruise to be painful at 3 weeks is quiet normal. All you need to do is to give rest to the part but maintaining the range of motion of proximal and distal joint simultaneously. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
