hi im 20 years old and for the past year now ive been experiencing severe chest pains from talking laughing walking pretty much anything that requires any kind of activity.ive gotten blood, urine, gi tests with scopes down my throat. i have acid reflux and a high level of anxiety. i used to be a smoker but have quit several times and now have been off cigarettes for about a month now and none of these pains subside at all.i also have some kind of stomach digestion problem that feels like it affects my intestines.lots of people say its my anxiety or acid reflux but i know for sure its not my anxiety and i am now on my 3rd perscription of nexium and it doesnt seem to be helping at all. i can never tell if im getting better or if my problems are worsening because they always feel the same. i eat very plainly and never eat spicy foods. im doing exactly as im supposed to but the doctor can never find anything wrong with me. So i start to feel discouraged and feel as if they thing im just a hypochondriac with multiple problems. but i know this is just not true. i feel i have very serious condition that is more than what can be tested for or i just havnt found out the true diagnosis for myself.nothing i do makes any of these problems decrease.they either get really bad but never go away.until i sleep.every morning i wake up and im back to square 1 feeling terrible.and it takes me at least an hour to get out of bed in the morning because i know that if i get up too fast my day will go completely wrong. i have bloating problems,gassy problems with pains.sharp shocking pains in my stomach and chest that sometimes feel like somebody is making slicing incisions in my insides.extreme tightness and im just getting fed up with life and knowing that i care about myself and im the only one that can take care of me! it hurts and sucks!
