I have sharp pains in the upper inner thigh near the joint when I try to stand, sit, or walk. It feels like a bone is going to break or crack. My knees are also bad; I have been diagnosed with degenerate bone disease. They can't seem to tell me what the sharp pain in the upper inner thigh is, however. It's hard to stand and walk because it hurts so bad. Any advice on how to deal with this?
