Because the diagnosis was taken from me, not by my rheumatologist, but another doctor. I cannot see him anymore because he doesn't take my insurance. I am getting an MRI on my brain to check for MS. If I have something that's attacking my peripheral nerves, like if it was Lupus, would this test confirm to my doctors that I have nerve pain and sensations. I've had weekness but I've had no loss of muscle strength, I just don't see what this test is going to provide except a big fat negative result, and I am tired of having useless tests done. If it could confirm that it's peripheral neuropathy instead of central, then great, but if it can't confirm anything, because I haven't lost any muscle strength, then I'm not interested. I have heard how painful this test is. Not exactly something to look forward to. My doctor said they can only keep the nerve pain under control, not the sensations. I wanted to screem when he told me that. Difficult to treat, that really sucks.
