My 14 year old son had the following symptoms- diarrhea, light headedness, fatigue. Dr. put him on 2 Prilosec a day + high fiber diet. Shortly after he complained of chest pains and still has pain but only when he lifts something. Could the chest pain be muscular or do you think it could be related to his diarrhea or the meds? Since he has changed his diet and been on the Prilosec he has not had any diarrhea.
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of musculoskeletal pain is more likely because your pain is associated with lifting (movements). So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Take painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected areas of chest. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
