Hi, my problems started after i took just one 40mg simvastatin - I then started getting muscle spasms, twitches weakness, fast heart rate, a thirst that couldnt be quenched and really dizzy along with sounds hurting my ears, and the feeling of water in my head. Anyway I ended up getting admitted to hospital because my heart rate was around 140 for no apparent reason, they done echos and monitored me for three days, but I found that when I moved around my heart rate went up, they then did a stress test, and before I even started walking on the treadmill, my hr was 110, to which they said oh hang on, i think sat down it was 90, they said the stress test was normal even though my hr got to 200 bpm, which my hr roughly is 196 given my age 24, so i dont know why they said this was normal especially since ive been a boxer, and interval and weightlifiting training i have done not a month or 2 ago, a 12 minute treadmill test walking fast walking at the end shouldnt do that to me. But im frustrated with this. They tried to say i was anxious or it was because i maybe hadnt done exercise for a few weeks, Anyway after wards i felt like instantly sick, and started to sweat, like into a cold sweat, I had to sit down and felt better but then i got pvcs, after and theyd took my telemitry off. Anyway i was discharged and given a heart event monitor. But i also bought a pulse watch and ive found that if i lay down my hr is around 70, if i get up it gets to about 105-110, 90 on a good day, and if i eat too much or something i start to race to about 130. This seems like POTS. But the doctors didnt seem to know what was wrong with me at the hospital and they are supposed to be a good cardiology hospital. I also get dizzy still find it hard to think sometimes and my arms seem to go cold, the muscle spasms continue. Anyway my problems have persisted even after three months although they have got slightly better but, I literally get a flush of heat in just one foot randomly no other area gets hot. My question does this sound like dysautonomia? and if it is, it is kind of crazy a statin pill could do this. I have a history of anxiety and panic attacks so I dont know how the heck i can convince them this is real, my gp dismissed me completely and said it was all symptoms of panic even though i had abnormal ecgs. When i mentioned my nervous system they dismissed it at the hospital again.
