Dr, My Doctor Left Me An Inhaler When He Came

Dr, my doctor left me an inhaler when he came on Thursday lunch-time,and,a prescription for Lansoprazole 30mg & Cyclizine 50mg. I have been taking them as prescribed & my pains have gone down slightly,but,before he left,he told me to get in touch with an On-Line doctor. He suggested that I may have Gall-stones. I would like to know what the symptoms are so that I can cross-check one with the other. Thanking you in advance. MR T D WATKINS
