I am 43 and in good physical health. I am a fitness instructor and teach 8 classes a week. I am suffering for about a year now with seizure like activity, screaming uncontrollably, muscle twitching, spasms, vibrations in head and back, inability to function at times, hyperplexia symptoms, very high bp and very low bp. My body doesn't like when it is at rest, so it happens when I am sitting in a relaxed position, as long as I am standing, or moving, I feel pretty good. I have seen ever dr. Imaginable, I have had an MRI, MRA, echo, EEG, EKG, and all have come back clean. I am very frustrated, I have been offered all kinds of drugs, that I will not take because my health is not a guessing game. I just want and answer, I am tired of feeling like this. Is there anyone out there who has some of these same issues, if so please share, and I hope for an answer.
