Nope, no explanation, no medicine, nothing whatsoever. :/ Lucky I just saw my GP today and she's trying to book an endoscopy asap. Good thing to because I'm feeling worse now - burning throat, constipated and it's hard to keep everything I eat/drink down. Very breathless too; anxiety of all the other symptoms doesn't help that but unless I take a deep breath myself - while standing or sitting certain ways - I become dizzy, lightheaded and my hands go weak.
I'll need to kick something if my anxiety was caused by Hiatal Hernia all this time. I'm just praying I don't have the dangerous version, being constipated and all. :(
