### input:
I wake up to horrible, back pain every day for a couple of years now. It feels like the middle of the back in the lungs. It s hard to breath and feels like my lungs can t expand without the pain. I end up waking up and staying up very early and I am now feeling a lack of sleep everyday. I suffer with acid reflux been on omeprazole very long term with known side effects now, so I recently stopped taking the pills and now drink a few swallows of probiotic Kefir which helps more then the pills. The pain in the back (Lungs) goes away once I am up and about an hour or so after getting up. A CT scan with contrast showed clear lungs.

### output:

Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having HERD (gastroesophageal reflux disease) mostly. Since your CT thorax is normal, no need to worry much for pulmonary causes. You are having mostly HERD. 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 burning chest pain in center of back. You need to follow these lifestyle modifications along with Chat Doctor.  1. Avoid hot and spicy food. 2. Avoid stress and tension. 3. Avoid large meals, instead take frequent small meals. 4. Go for walk after meals. 5. Keep 2 - 3 pillows under head in bed to prevent reflux. 6. Avoid alcohol and smoking, if you have these habits. 7. Lose weight if you are obese. Don't worry, you will be alright.
