So for maybe a year now I've been having problems with heart palpitations (namely just a really loud, pounding, fast heart whenever I lie down and some other times), shortness of breath and trouble breathing until I manage to get my breathing back on track, some pain in my knees, elbows, and mostly legs that make it hard to pick up things or walk sometimes (the pain comes at random intervals) and a few other symptoms that I think are visible on my profile.
The heart palpitations are most predominant just after I've laid down at night to go to bed, so is the shortness of breath, although both can randomly start during the day. I've always felt like my heartbeat is too strong and 50% of the time it's pounding in my chest. The pain starts at random intervals, and will all of a sudden show up. Sometimes I walk with a limp or can't write or pick up things properly because of this - sometimes my hands get stiff as well, although I suspect this is only because I play several musical instruments, so I'm sure this isn't much to worry about.
It's getting kind of annoying but my mother doesn't seem too worried about it, should I be? I'm fit, within the healthy weight for my age range, and I walk everyday. I have psoriasis and used to do UV treatment before switching to methotrexate (and folate) tablets, but I am off medication now and these symptoms did not appear until after I was off my medication. I hope someone can provide answers
