I have an extremely painful right knee, even when resting. Was referred to physical therapy by a walk in doctor after being told there was too much swelling and guarding for a proper exam. Have been in therapy for 5 weeks but the symptoms persist. The symptoms include pain in and below the joint, swelling, instability, catching/grinding, decreased mobility/strength, and sometimes numbness and tingling below the knee and into the foot. I now walk with a pronounced limp. Have tried the usual R.I.C.E., Anti-Inflammatories, and a brace. Had the knee reconstructed 13 yrs ago after a dislocation injury that recurred. Currently an active 27 yr old female. Is it time to forget the therapy for now and see a specialist? Any idea what's going on?
