Im a 20 yr old female who for the past month or so has been having chest pains,crying,bad dreams,sometimes its hard to fall asleep,twitching in my chest,sometiems shortness of breath,burning in the back of my leg and upper thigh,my legs take spells shaking after standing to long its like im nervous or something,i get these cold/hot flashes like im cold one min hot the next freaky i know.I also get this weakness feeling in my legs,stomach,arms. I keep check of my BP and it stays normal i mean like 106 over 73 sometimes alittle higher than that, and i am alittle over weight but idk what it is that causes these i take it by days its not a every day thing just when i get aggervated or i dream something.I think its bc of stress/anxiety.
