I'm hoping someone can help. I have been cancer free for 1 year now and I have been getting very sick anytime I over exert myself ie.shaky, nauseous, vomiting, light headed. Etc. I went to my onc and she didn't know what was going on so I just went to my primary care. He told me he believes it's a sympathetic nervous system discharge( over active sympathetic system) has anyone else ha this and what did you do to help resolve it? He wants to put me on a beta blocker!
