### input:
For a few weeks now I ve had weird sensations around the chest and down the middle of my chest bone. It isn t a pain but a strange feeling. Sometimes it feels like a burning sensation. Sometimes when I take a deep breath I might get a sharp pain by a pec or in my ribs. I feel OK taking a deep breath other than the burn/warm sensation down the middle of my chest. I ve had the full heart scan and that was clear and also doctor has listened to my heart and chest in the usual dozen places. I ve now had blood taken and waiting on results. I m also waiting for an xray appointment. I have Addison disease, don t drink or smoke. I m a 36 year old male. It has been like this for about 3 weeks now.

Thanks for your question on Chat Doctor. I can understand your situation and problem. Since your cardiac and pulmonary examination is normal, no need to worry much for major problem. In my opinion you are having HERD (gastroesophageal reflux disease) mostly. It is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the burning central chest pain. It is also common in Addison's disease. So HERD is the likely cause in your case. Try to follow these steps for better symptomatic relief.1. Avoid hot and spicy food.2. Avoid stress and tension.3. Avoid large meals, instead take frequent small meals.4. Start proton pump inhibitor.5. Go for walk after meals.6. Keep 2-3 pillows under head in bed to prevent acid reflux.Don't worry, you will be alright with above-mentioned lifestyle modifications.
