Shortness of breath, rapid heart beat and pains in chest and back...? I stress alot, and i have an anxiety problem... i have pains in my chest and back, shortness of breath and rapid heart beat ALL the time. Also i am tired ALL the time. i Have to sleep at least 10 hours a night or i will be exhausted.... went to the doctors and they said i was fine. i dont have any more insurance so im not going to be able to go to the doctors anymore. I have OCD and was wondering if anyone else experiences the same things?
