Hi, i m a skinny male (24 years of age) some would say, ectomporph with a history of what i have been told is anxiety my symptoms being cold clammy hands, very strong pulsating heart beat usually feels too fast for my body s relaxed state (no breathlessness). Also, I cannot do much exercise such as lifting heavy objects for very long. I get a racing heart and go dizzy and have to sit down but NO shortness of breath? I have ignored it for some time as the doctors have explained to me its anxiety but I have been trying to say that I only get anxious when the symptoms occur. I get anxious over my health not, anxious before the symptoms! there is nothing to be anxious about! My question is, is it possible my doctor is overlooking something, or is it just some sort of stange anxiety disorder? thanks, Justin Turner.
