Hey I was reading through all these posts and I can relate to a lot of these symptoms. I have had burning, tingling, numbness in feet and legs and sometimes arms and face. It's getting worse and I'm at the point now where I avoid walking and standing at all costs. I have been told I have nueropathy and that there is nothing I can do for it. Okay so I went back to neuro last week and he is running tests again for MS. But I have these vibrations and light sensitivity etc. He said if these test come back normal then I think you have Fibro. I just want an answer to all this. I starting to get depressed because this is all progressing so rapidly and I feel like I'm losing my mind and I will be unable to function before too long. Sorry to ramble. What is PD?
