@park682 -- I totally understand you!!! I went to the dentist today. the clinic was located on the 3rd floor and there was no elevator so i was a little worried what if i don't reach the 3rd floor and explode but i did reach the 3rd floor and i felt a little fine then just after a few minutes after while seated in the clinic waiting for my turn i felt uneasy with SOB
then while the dentist was cleaning my teeth(i am terrified of the instruments esp the sound) i was in total panic and i was holding my breath but for some reason being in that panic mode -- NO SOB!!!
@playmaker093 -- yes i do have chest discomfort but not all the time. however my muscles seem to always be tight -- chest, shoulders, arms, back, neck and legs. also, i don't yawn instead i keep on burping.
