[|AI|]  Hello there, Thanks for your post on Chat Doctor. I carefully read your problem and able to find your point of concern. I think you are suffering from initial stage of knee joint arthritis though you didn't mention the pain. Due to overuse of the joint the sign of inflammation like redness, swelling, local temperature, pain will increase. I think your conditions is for that overuse. You can try hot and cold compression, if pain present then painkiller like ketotolac, Naproxen, Ibuprofen, along with omeprazole or pantoprazole can use. If remain unchanged you should consult with an orthopedic doctor who may aspirate the joint fluid for cytological examination, and give intra-articular steroid and other necessary treatment if needed. I think it will help you. Wish your good health. Regards
