I have episodes of dripping sweat after light activity, dizziness, heart palpitations and feel like passing out. It's year round. When I shovel snow I get feverish, sweaty, cough and vomit. I have rheumatoid arthritis, chronic bronchitis/asthma. I recently had a stress test, which came back normal. I am trying to figure out what is wrong with me so I can discuss with my dr.
