Thanks! I haven't seen a doctor for GERD, but my housedoctor told me to try medicine for my stomach, but it didn't help. I have done a breathing test (spirometer, not sure if its the same name in English) and the results were excellent. So in my case I think this might be caused by a few things together: by back (bad working positions at home), some kind of stress/anxiety that I haven't really found the cause for yet (maybe the whole covid situation and not being able to live as usual) and my riding accident which might have lead to me not breathing properly.

But it's just specualtions and im trying to map things that happen around when this is triggered. Yesterday I had no problems at all but they started a bit this morning when I travelled to my office (I usually work from home). Sometimes I might stop it in time if I focus on breathing right but other times I cant stop it. It's frustrating.

Have a nice day
