<s>[INST] I fell about a week ago and hit my knee really hard--I thought it was just scraped, but the entire knee is now bruised.  I also have some swelling, a few tender points, the knee feels stiff, and it is a bit uncomfortable to walk on it--the cut part is healing well.  I seem to have a really high pain tolerance and have broken bones in the past without realizing it.  I am pretty sure I need to get it checked now, but should I go to my regular doctor or what? ( F, 59 years old, but very active and in good physical shape). [/INST] Hello,If you have severe pain that you cannot bear weight on your limb,suggest you to get an x-ray to rule out any fracture.Otherwise ,ice application,elevation,crepe bandage and analgesics will suffice Hope this information helps </s>
