Went to my cardiologist this morning.. got all checked out again.
It is not my heart..
It is not my MS..
it is.... *drum roll* acid reflux! uuugghhh
sad thing is I have been taking something for that for a few years now.. never had it hit me like that before though, guess it is time to call my PCP and see about getting a higher dose or different med. at least that is all it was.
