Methylprednisolone
"I am currently on this medicine for an inflamed sinus cavity, with 2 more days left. I have been experiencing HORRIBLE backaches to the point of wearing a heating pad on my back the past 3 days, the stomach cramps, constipation, fatigue, extreme thirst, UTI like symptoms and insomnia I've been experiencing!! I didn't know would happen, my pharmacist didn't really mention all of these side effects to me when I got this pill. Anyways though, I have NOT been able to breathe out of the one nostril and the other was barely open too which makes for a very difficult night of sleep however, this pill has done wonders! Within the second day I was able to breathe and lay on my one side which is something I haven't been able to do in a long time!"
