Big hair symptoms and conditions

I recently noticed my hair was thinning, long strands coming out in the shower, and extremely dry. I had thin hair to start with, so can't afford to lose any hair. I read all these postings where others have had hair loss from Lisinopril. I started taking it the end of August and in the past few weeks have noticed the hair loss. I put in a call to my doctor and am waiting for his return call. Lisinopril has been keeping my BP's almost perfect, but what a trade off. I'm wondering if taking extra Vitamin E or Nioxin which promotes hair growth would overpower the effects of Lisinopril. I've also felt a vibration in my left thigh that comes and goes and my thigh heats up once in a while and goes away. Anyone had that side effect?
