I have been experiencing pain in my chest and on each side of my chest (once through to the back) all day. This started after eating my bowl of breakfast cereal and bananas and taking my morning meds.. Most of the time it feels like indigestion, but I have no heartburn. Three times, if has been really bad. Is this my gall bladder? p.s. I take Omeprazole for GERD every am. Other meds I take in the am, after breakfast are Lorsartan, aspirin, 100 mg. of Nitrofurantoin, and 1300 mg. Garcinia Cambogia (for energy and weight loss). Upon first awakening, I take two thyroid meds.
