Hello everyone, I have Crohn's Disease but I'm not sure if this symptom is related, if it's just gas, or if it might be something else. I regularly get an aching pain under the rib cage and my left breast right around where my heart is. It's scaring me a lot since it's so close to my heart. I belch a lot (which smells like rotten eggs) and am just wondering (and hoping) if this could all be gas related. But nothing seems to fix it, I've tried all the OTC gas remedies and various prescriptions that my doctor has given me. Does anyone else experience this? If so, do you know what causes it?
