I found out how important it was a couple of times: when I had pneumonia twice and when I had methotrexate lung. Not being able to breath sucks.
Starting yesterday I noticed I was getting out of breath going up the stairs. I was also coughing like crazy. Today I am not coughing very much but my chest feels like I have a band around it and I am out of breath. The question is, is it the doxycycline or is it something else like pneumonia?
Tomorrow I will call the doc if it doesn't get better. Breathing is pretty important.
