I have had a muscle myopathy in my thighs for years. Two years ago, I had a total knee replacement. I am 61 years old. I have been getting weaker and weaker. I can t stand for more than a couple of minutes and I have to sit. I have lots of pain in the knee and mostly in back of the knee. The weakness worries me. When I say weak, I mean weak. Trouble just to take a few steps. Have been to the Dr. and he does not know what it could be even after diff. tests....
Hello, Your symptoms could be related to the progression of myopathy or a pinched nerve. For this reason, I recommend consulting with a neurologist for a physical exam and performing nerve conduction studies. Hope I have answered your question. Let me know if I can assist you further.
