Hi, i was having this acid reflux things 2-3 days back due to which i was hving chest tightness in left side from neck to chest and in back & also was feeling pain near throat, also i had blocked burrping then i checked wid doctr she said its acidity...now acidity is better but i feel warm in my neck and yes i felt pain in back near neck too since 1 months due to sleeping on left hand.. I am not able to explain since i hv faced lots of issues for the first tym wid my body and all one after another so i might linked up my acidity with my neck warmness but i dont know what it is..also whenever i turn my head upside down i feel cold in nose , may be smthing flowing towrds head..its unexplainable.. dont know wht to do...i do feel i breathe too slowly..
