Multiple symptoms from different sicknesses, all showed up at once. First i got very light headed, sick to my stomach and distorted hearing while driving, think its caused by a bad sinus or ear infection, however dont feel the symptoms I usually feel when i get them. Also i had an anxiety attack with hyper ventilation after experiencing shortness of breath, onset by rubbing my upper abdomen, that lingered for about two days, until i had a deep burp from my stomach which relieved pressure allowing normal breaths. Since then i have been having constant deep long burps, like after chugging a beer, but havent really ate or drank anything besides water since the anxiety attack, this sensations is made worse when sitting up with my stomach ontop of itself. Also ive been experiencing muscle weakness since the day before the anxiety attack. Is it possible for this to be all in my head, im a fairly inshape 22 year old who does not drink, smoke, or use drugs. Therefore this seems very odd to me. any insight?
