I know some of this can be coming from stress, for some reason, I tend to stress myself out very easily. I tend to be the easy going guy and get caught up in family or problems with friends, and it stresses me out. Almost every morning, I wake up with a little shaky ness in the upper left side of my chess. It s not my heart or blood flow...had an EKG plus a CAT Scan. Is this an Anxiety attach or what. In the pass I was given some medication call SERTRALINE HCL 500MG...please advise on this situation, thanks.
