[|Human|] Hi I fell heavily on my knee just under the kneecap area. It hurt like hell but after a few minutes of rubbing I could bend & stand up. The area was numb & still is 4 hrs later. If I press on the area it feels like a massive sting. I have had an operation which involved micro-fractures approx 4yrs ago. Do you think I need any medical help?
[|AI|]  Dear sir/ madam based on your description I would examine your knee for local bony tenderness. Most likely it could besot tissue injury to knee for which I would recommend rest, immobilization in a knee immobilizer, some analgesics, ice fomentation for 1 week. Then when the pain and swelling subsides examine your knee ligaments and then decide on further management. Numbness might be due to direct injury to cutaneous nerves or edema in that area, so after giving rest for 1 week further examination is recommended.
