GTN spray? and MORE

[FSKhan]

Hello, my question is, does anyone have chest pains, constricting especially during the winter, and is relieved by Nitrate spray? (GTN, usually used for Angina).  In addition, do anyone have MCAS ? (Mast Cell activation syndrome), or Gastorporesis ? ( sorry spelling is awful)

I have cardiac chest pain and with it feeling like I can't catch my breath. NTG helps a lot with the breathing when this happens, but my cardio thought it may make my systemic symptoms worse??? The gastroporesis used to be terrible, but am thankful to have a lot of improvement in that area. I'm sorry you are dealing with it.
