I have developed a hard lump on the inside of my leg, just below the knee cap. I run and do weights 6X / week (including squats, lunges, etc. on leg day). It doesn t hurt but now I have a large bruise just below it although I don t recall hitting it. Suggestions?

Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Treatment / Cause for hard lump on the leg-In my opinion your lump seems to be synovitis due to the Knee arthritis.-Avoid heavy work ups -as it may cause more arthritis.-Consult ER-Surgeon.-Take Anti-inflammatory tabs / hot fomentation / and rest to the part for 3 was at least, which would relieve you. Besides this being a continuous disease-I would advise ER-Ortho-Surgeon follow-up and treatment for next 6 myths time to get it under control. And hence needs ER Ortho-Surgeon check up and needful treatment. If not treated it could increase your leg pains and bruise constantly. So do check it up from ER Or tho- Surgeon. For Final Diagnosis and treatment needs clinical data from a Doctor. And Hence for further treatment I would advise you to Consult ER Ortho-Surgeon, who would treat it accordingly. This advice is based on the facts from the history you give and needs further clinical check.Hence, I would advise you to check with ER Or tho- Surgeon. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you. Hope this would relieve your problem.
