Friday he had a panic attack because he couldn t get a deep breath. Rushed him to the er they did a lung xray and an ekg both were normal. They then said it could be Something in his stomach . We ve uped his dosage of zegrid to 2 a day he s used dulcolax. Nothing seems to be helping. Is there anything he Can do for relief? Please help!!!!!
