I've been feeling strange for the past couple of months, and it's happened twice already. I get this itchy feeling in my throat, and there's a heaviness right in the middle of my chest and the tube that leads from my throat to my stomach. It gets really uncomfortable. Breathing feels really tight, although it's still okay, but then I also get this uneasy feeling in my stomach. After about a week, it settles down, but then I start having pain in my lower abdomen. I used pantocid before, which helped, but now I'm confused. Is this a gastric issue, something heart-related, or maybe a breathing problem? Can you offer any advice?
