I've never used a neurologist, only a neurosurgeon. I sure hope he gets answers from the and quick! I know the pain he is in, and it is no joke. Given the severity, it does sound like possible over draining but, only the drs opinion counts unfortunately. Honestly, in my opinion, over draining is probably the worst pain I have had with hydro but, laying down always helped me get relief. During the overtraining episodes, either the other symptoms "took a back seat" due to the severity of pain or were not existent.
