Hi, I'm not sure this is the right newsgroup to post to, but I couldn't find anywhere that looked more relevent, so I'll use this one. Apologies if this post ends-up rather long, but I'd appreciate it if you read it anyway and let me know what you thought as I'm rather concerned. Thankyou. About a year (or more) ago, I found that if I lay on my left side, I would experience palpetations, which I found rather odd, but -- with hindsight rather strangely, as I'm only 18 years old now -- I didn't think much of it, I just made sure I didn't lie on my left when I went to sleep. Anyway, since about 2 weeks ago, my chest-area has started to worry me. Sometimes I get aches in what seems to be my heart, which come and go, although they're much more common when I lie on my back -- they'll almost certainly be there after 10-15 minutes of lying down. It sometimes 'twinges' too, but not twinges of pain, it's a bit difficult to explain, but it's closer to a tickle than pain -- either way, a little bit disturbing. The last few days it's got more and more common as far as I can tell, and I've started to get other things too. For instance, now quite often I can feel sort of "fizzes" around the general chest area, and sometimes down my arms, legs and the base of my neck. I suppose another description (which I stole off someone) could be pins and needles, although I doesn't feel numb or anything. However, it's not very pleasant as I have no idea what they are, although coupled with the problems I've already mentioned, I find it a frightening addition. I went to the doctors' a few days ago and told her all this (but not about the 'fizzes' as they hadn't started then). She took my blood-pressure, which she said was 110/70. However, I think she was a bit distracted as I had had to roll-up my sleeve for the blood-pressure thing, which exposed my scar-covered arm from when I used to self-injure a few years ago (what can I say?, I'm a mess). I think she just looked at me, a young, underweight person and decided that this was probably more important than some (perhaps in her view) phantom heart problem. She said that there was nothing wrong with me, and the aches were caused by something-or-other rubbing against something else, although I'm afraid I can't remember exactly what she said very well. I wasn't convinced though. My mother, who's a nurse, just thinks that it's stress, as in the last few months I've had a driving test, extremely important exams which will decide the rest of my life, as well as other stuff. I really don't think this is caused by stress, it seems far too extensive for something as simple as that. And I know far better than her how I feel. My diet used to be quite poor (hardly any fruit and vegetables at all for rather a long time), although recently I've began eating much better, with what I would say is far below the maximum limit for fatty foods, and I now eat lots of fruit, etc. However, since I left school after the exams, I haven't really been very active, and it is since then that the aches have begun, so I've started just walking around aimlessly to try to get active again (but only in the last few days). I also played some sport with the rest of my family (partly as a response to my visit to the doctor), but I found that my chest began to ache after some running around. In short, I can't see at all how there can be nothing wrong with me, yet everyone else seems to think there isn't. Earlier today I had to pick my mother-up from the hospital in a car, and, despite getting enough sleep last night, I felt very lethargic. By the time I'd got back home, I found I had to reverse into quite a tight space to park. But I couldn't be bothered, I just wanted to get out and do something else, I didn't care if I parked elsewhere, so I did -- across the road instead. Once I got in, I completely fell apart emotionally, and went to my room to try to recompose myself. I'm getting so worried about this thing -- that only I seem to think is serious -- that it's probably not doing the problem any good anyway. Please (if anyone's still reading this stuff), can someone tell me what they think. Surely this isn't normal, surely I have some sort of problem that needs urgent attention? Should I go back to the doctors', or perhaps a hospital or something? I'm very worried. If you're still reading, thanks. The ache's been here the whole time I've been writing this, BTW.
