hello i am experiencing a mild chest soreness that is substernal and is felt mostly at maximum inspiration/expiration. i first felt this about 1 month ago and although the pain/feeling has subsided , it is still present. my ck/triponins,ekg/cxr were all wnl. i did however start lifting weights again about the time of the chest pain onset... your opinion is greatly appreciated.
Thanks for your question on Chat Doctor. I can understand your situation and problem. Since your extensive cardiac work up is normal, no need to worry about cardiac cause. Substernal chest soreness is mostly due to HERD (gastroesophageal reflux disease). 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 symptoms of burning pain or soreness in central chest. So try to follow these steps for better symptomatic relief. 1.  Avoid stress and tension. 2. Avoid hot and spicy food. 3. Avoid large meals, instead take frequent small meals. 4. Start proton pump inhibitors. 5. Go for walk after meals. 6. Keep 2-3 pillows under head in bed to prevent reflux. Don't worry, you will be alright.
