As you already have acid type pain, it could be acid reflux and shortness of breath can be due to acid reflux rather than any lung problems, so you may possibly be on the wrong meds.
Anyway, I would strongly suggest that you go and consult an ND and go down the alternative. This would make a lot more sense for you, especially as you hate taking meds and react badly to them. ND's are train in homeopathy, acupuncture, herbal medicine and naturopathy, all of which could really help you.
Good luck
