At work tonight and i have gerd or acid reflux and i am out of meds... that being said, when i take a deep breath i get a sharp pain in middle of ches?

Mastic Gum: Pain with respirations, coughing, sneezing is usually due to pleuritis (inflammation of the pleura). The treatment is usually aspirin--but with your GERD, that might not agree with you. Try another over the counter anti-inflammatory like the herb, Boswella, from a health food store. For GERD, I recommend Mastic Gum, also from the health food store--1,000 mg/day for at least two weeks.
