I had eye surgery 2 weeks ago - supposed to be in and out procedure - oxygen levels dropped so they did a chest x-ray and found that I had pneumonia. I was put on pills 2 first day, 1 each day for 3 days. Got a little better and went for my eye followup and was put on sulfamethoxaz?? (can t ready the rest of the picture) were these good for pneumonia? I am starting to cough again, no fever - I have a million things wrong with me - type 2 diabetes, asthma, sleep apnea, overweight.
