<human>: Hello, I feel like I have an air bubble lodged underneath my knee cap. I bent my leg wrong during a game of Twister, and now I can t bend my leg more than 120 degrees, after which I feel like my knee cap is going to dislocate. This is excruciatingly painful, I get a very cramp-like feeling with a high amount of pressure on my knee. What could be the matter, and what should I do?
<bot>: Hello, It looks from your details that most probably you may be having post-traumatic synovitis of knee. There is swelling of covering or associated soft injury at your knee. You should do following to have relief:- Take rest-Apply a knee support like knee cap-Take a good anti-inflammatory analgesic We used to prescribe diclofenac or other similar substances in such cases. If this does not improve your problem in next 3-5 days then you should consult to your doctor and should have an X-ray of affected knee. Hope I have answered your question. Let me know if I can assist you further.
