I am a 28 year old female with a number of autoimmune disorders - fibromyalgia the most recently diagnosed. I am currently on Lexapro, Zegrid OTC, Flexeril, Singulair, proventil inhaler, claritin, 25mcg synthroid, and I also take vit b complex, c, and d daily as well as a kids multivite. My question is that in the past several months, I have been unable to achieve orgasm without great difficulty (by myself even - and I used to be able to do that incredibly quickly without any problems. When I do orgasm, my legs and arms go numb and very painful, and my heart beats out of my chest, and I feel like I can t breathe. I had an EKG in november that was normal, but I have had several incidences of tachycardia including when I was woken up from general anesthesia after ovarian surgery. Could this be a heart problem even with a normal EKG?
