Another odd symptom that started the same time that my neuro symptoms did was my inability to give blood. When the nurse puts a needle in me the vein visibly constricts. Blood will gush into the vial for about 1-2 seconds and then abruptly stop. They usually have to stick me 5-6 times to take blood.

Never had a problem before the neuro symptoms. Related? Any known cause for this?

Also, I think the fact that my severe bladder issues switch on when my tingling and numbness switch off, and vice versa, should be a solid clue for a neurologist?
