I think I might have an auto-immune problem, have been tested pretty extensively for neurological problem with no abnormal results or concrete diagnosis. I've been tested, diagnosed, or checked for hemiplegic migraines, fibromyalgia/chronic fatigue syndrome, low blood sugar/hypothyroidism, pre-diabetes, and strokes/seizures; none of these are actually likely to be my issue and the last three were tested and came back false.
I've made an in-depth Reddit post about my issues here: https://www.reddit.com/r/AskDocs/comments/9mxq0s/possible_autoimmune_disorder_or_neurological/
