I've been having a drained, weak, lightheaded pain in my head for 6 months. My muscles in my shoulders, arms, and trunk often feel weak, rigid, electric, and generally uncomfortable. I also feel the need to stretch them a lot, but the stretching never makes them feel better. I also was diagnosed with Gastroparesis in January, but have probably had it for more than a year.
My baseline blood work has all been normal, except for slightly low Vitamin D levels. My ALT and AST liver enzymes were elevated for over a year (At one point my ALT was 256 I.U./L), but they're normal now. I’m taking Vitamin D3 and Vitamin B12 supplements, along with a liquid multivitamin. I've had an MRI of the brain, which was fine. My serum copper was normal. I'm awaiting an order for my urine copper levels. I exercise daily and I get a good 7 hours of sleep every night.
What could be causing my symptoms and are there any other tests I should have run?
Thank you very much.
