Ive been having difficulty,sitting and getting up.The muscle/tendon?just above the knees really hurt when I flex my knee.There is no pain when I sit ,stand or walk.Only in the process of sitting as I lower myself,or getting out of a seat,theres a lot of pain.Xraus show normal wear and tear of the joint.Sometimes the area just above the knee feels hard and swollen.
You haven't mentioned your age & your work type. You seem to be suffering from Often arthritis. Take a course of NSAIDs like Tab prior DT twice daily for a week & see, if not relieved a dose of intra-articular dose of Tricorn will surely help you, the hardness you feel above joint is due to stiff knee & spasm.
