Well my knee has been hurting for a couple days now and at..first I thought I may have bumped it and it was just a bruise....however there is no bruise....I was lounging on my recliner today rubbing it and rubbed a spot that hurt badly...it has a small pea sized ball I can move around with my finger.....what could this be? And should I go to a hospital?
Hihope this msg finds u in good health. I have gone through your complaints and understand your concern. U seem to have injured some sort of soft tissues in that region causing fluid accumulation. Apply ice packs take analgesics and anti-inflammatory tablets. Take rest get a X-ray done to find out what's wrong. Nothing to worry about. Hope your question has been answered. If u have any follow-up queries, feel free to consult me anytime.  Thanks Take care god bless no need to
