Does electro galvanic stimulation work?

Crippling elevator ani spasms have all but ruined my life. The specialists that I could afford when I still worked won't even talk to me now that I am on Medicare C program. In fact, I can't afford anything but the free annual physical. All my prescription medications have zero co payments this year. Since the left has taken away painkillers that work, and have worked for over 20 years, I'm having to find alternative means to remain mobile enough to take care of myself. Any way to get gainful employment? Also " deaf as a post" per my last DOT physical, and not a dime to buy " hearing" again. I'd be scared if I could afford it.
