upper respiratory tract infection
"Within 20 hrs (2 doses) I was feeling better. My lungs still hurt when I would cough but they didn't hurt when I would take a shallow breath. I did get a pretty bad headache that was controlled with APAP.  Loose stools developed after day 3. I increased fluids and fiber (ice cold smoothy worked great to fulfill these). Day 6 I was back to normal except the loose stool. No other complaints. I was also on pearls and codiene during this time. Side effects well worth benefit after how bad I was hurting."
