Methylprednisolone
"I'm a 47 year old dog groomer. I was prescribed 4mg /6 day pack for a deep root nerve inflammation in my neck due to an injury from a dog. I weigh 112 lbs. After 2 days of using this med, I went from 112 lbs to 119 lbs. I was in such a fog ; almost loopy.  My legs and joints hurt severely. I have been retaining water mostly in my legs. I read up on side affects. I stopped using this med and began drinking lots and lots of water to help with the water retention. It did help with my pain very quickly, but one needs to weigh the pros and cons. I'm now wondering how long it will take to lose the near ten pounds it put on me. I'm a very healthy eater. No fast food, soda or carbs. Caloric intake is still the same. Time will tell."
