<human>: I fell a few weeks ago damaged my ankle and wrist but also banged my leg about 2 inch under my knee on the edge of a step. Almost 5 weeks on it Isla extremely painful and burns inside if I press or kneel on it. There is slight swelling but no bruising... What have I done to it?
<bot>: Hi there. Thanks for your question at Chat Doctor. With the history of injury and swollen painful knee(as in your case), an examination by a doctor and an x-ray will be needed if:1. You are not able to walk on your affected knee(not able to take any steps without pain). 2. you are not able to bend and straighten your knee to the fullest extent(or your previous normal range of motion). 3. There are any areas of your knee which are very tender to touch(after you feel all the spots of your knee-all around). 4. If you are elderly, say more than 55 years (your chances of major injury increase with age). In the meantime- rest, ice application, elevation of the affected leg and painkiller medicines can give you some relief.(maximum relief in initial 48 hours)Hope this helps. All the best. Regards.  Chat Doctor.
