Ok! I really don't know from where to start. I'm in the hospital from almost 4 days and no one seems to know what's wrong with me and doesn't seem like they care either. 4 days ago I was at the dentist and he inject me with an anaesthetic. After about 15 minutes after that I started to shake with my whole body my blood presure went to 170/90 they called ER but before they got there I was already stabilized. So I went home and all day I felt my heart like it was a little bigger. In the morning I woked up refreshed myself and when I started to have breakfast I got a little dizzy and my heart beat went super fast. Not a while after I started to shake with my whole body( I am not cold, I just shake), so I called 911 and they put me an injection for lowering my BP it was 160 somewhere. So the same day I got into the hospital and every morning when I woke up I get this rapid heart beat, I start to shake and my blood presure is rising instantly....after the injections my blood presure is normalised 120/80, but I can get worse anytime again...however this morning was different because yesterday i got some pills and for now they seem to work because this morning I was again shaking but with less heart beat and it released me in 5 minutes, but my blood presure was 90/55 and after the shake it was 100/60 i guess it's from the pills....but still no one knows what is wrong with me and no one can give me even some suggestions. For now all I know is that the ECG shows that everything is normal and doctors tell me that is from stress which I don't believe is true. I am 20 years old, athletic type, I have a really strong and happy relationship I can't stand doing nothing all day, I go to run, fitness, i play tennis and etc. I suggested the theory that it's from the anaesthetic that the dentist put me, because all this started from there but for the doctor it's just a coincidence. Oh and I forgot to mention that sometimes my heart beats so strong that i move with the bed literally.
