Nerve Study for Fibromyalgia

I have two areas of permanent brain damage (not getting worse, but also it's as healed as it will be) and also nerve damage in my right arm, this was found via MRI when I spoke about my arms getting paralysed for a day or two at a time sometimes. I've since developed seizures. Still no further investigation, no diagnosis, no check ups 🙃

I've had the test and it came back normal
