I'm a 25 year old girl, and as of about a week ago, I have consistantly been experiencing strange cramps and numbness in my hands and arms during and after intercourse (has occurred now 5 times). It generally begins as a tingling (think as if a limb were falling asleep) in my fingers and toes, along with muscle twitching and cramping in my face (mild though) and rises into almost a paralysis in both arms. It sounds really strange, but my hands and arms become so cramped almost instantly, and they sort of lock into place like a doll or something. My face continues to twitch and it takes about 5 to 10 minutes for everything to "release". It isn't only when I orgasm, but it certainly is exacerbated when I do. I run and work out daily with no problem, and eat very healthy (vegetarean but still eat some fish and shellfish) so I'm not quite sure what's going on. I don't think it's muscular otherwise my daily workouts would be affected, right? Any Ideas? I looked on wrongdiagnosis.com and a slew of crazy diseases showed up... just wanted some real feedback- I (and my boyfriend) would really appreciate it.
