Yes, I have recently recovered from a cold and during the cold I was given a antibiotic that I soon found out I was allergic to. I was treated for the allergy in the ER and given a different antibiotic. The reaction I had was a narrowed esophagus and I could bearly breathe. That was a couple of weeks ago and I have since recovered from the cold but now I am experiencing severe pain in my chest if I sneeze , cough, and I even get short of breath easily when climbing a single flight of stairs. I m not sure what to make of this but it feels like my lungs are going to explode when I cough/sneeze???
Hi, Let me ad Chat Doctor.  1. I hope you have completed the course of second antibiotic, which you are not allergic to. 2. If you have completed the course, then make sure that you are not taking any other medications. Since, medications usually cause heavy breathing, shortness of breath, it is better to avoid any medicines as such unless they are required. 3. I do not know your age, I am sorry. However, it is advisable to get an EKG done to look for the cardiac status. 4. Repeat a chest X-ray now and look for signs of residual congestion on the lung fields. 5. It is better to consult a pulmonologist and get bronchodilators prescribed (IF required only). Hope this helps. Get well soon.
