I have been taken to the hospital twice in the last 4 months by ambulance. Nauseated, almost fainting, sweaty palm then cold, shakes. Next door neighbor is a nurse and the first time I called her over as I was alone at the house. Last week I was at work and our nurse there was with me and decided to call an ambulance for me to go get checked. Both times I needed to lay on the floor to ensure I would not fall. Heart test good, blood pressure good, Stress test good. Wife is going through chemo for pancreatic cancer. First time I was not sleeping and very stressed and nervous. Treated as anxiety. Was off work 6 weeks. I am 53 years old and in good shape. Should I ask for certain tests to be completed?
