I m a 49yr old male 5 6 148 Lbs Smoker Non- Drinker. Today while on work break, I had a sudden onset of Nausea, Dizziness, short rapid panting breathing. this is the second time within 4 months this has occurred with the first time being the worst. the thing I did notice that confuses me is the passage of Gas and the need to defecate. after passage of Gas and defecation symptoms slowly subside and life goes on. I have NO major medical issues aside from High cholesterol and it s managed with Lipitor 40 Mg. I also take Hydroxyzine 50 Mg PRN which I recently felt the need to take in the last 48 hrs after NOT having to take it for a couple of months. So my question is, with the above description. is this a potential medication issue, GI issue or Cardiac?? My intent is to get into see my Reg. Dr., but the VA moves slow and you re opinion will help me decide whether or not to Circumvent the system or not, as there are repercussions for doing so.
