Hello I m 14 years old and for a couple weeks now I have been having knee pain . A squishy lump appeared right beside my knee cap but is only visible when flexing or bending the knee completely. The pain is very minor o the lump specifically, but my knee itself does hurt. My trainer said I have tendinitis, is that what this lump is caused by?
Hi, thanks for writing to Chat Doctor. Well, I also agree with your trainer; this kind of symptoms generally relates to sprain/tears of tendon or ligaments due to strenuous exercises! There could be some loose bodies, synovial fluids or minor injury to patella, muscle or the tendons! I also suggest you to go for an X-ray / CT scan microbiological/cytological test of the secretion for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
