I have breathing issue through nose and chest diaphragm. I can't breath fully, a short breath. After X ray doctor told its cough in chest and even I have acidity. So along with cough syrup doctor prescribed for acid reflux tablets. But still I didn't recover(slight improvement is there) after 3 visits. I have done RT PCR, which is negative. Oxygen level, respiration level are normal. What could be done? Info: I have lower back pain/slip disc as well
