Hello, thanks for posting your query on HCM. It seems from your post that your pain is significant- with difficulty breathing. I suggest you see a doctor at the earliest, rather than take over-the-counter painkillers. Pain that is persistent/increasing must not be ignored. You need to know the origin of the pain to treat it effectively. Your doctor can examine your chest and abdomen, ask for blood tests, ultrasound etc. and give you medication. Common causes of abdominal pain are kidney/ureteric stones, bowel inflammation/infection, gastric ulcer to name a few. Continue to maintain good hydration, and avoid spicy oily food. Hope this is helpful. Take care.
