I went to the rheumy today for pain. He gave me this 6 day MethylPREDNISolone pack to take. He mentioned the word cortisone, but I am scared to take it. It has 23 pills that you are supposed to take within 6 days. I saw the word that resembled prednisone and thought oh no I might swell or gain weight. Has anyone ever taken this, and if so did it make you gain weight or swell. Did it seem to help? Know med. is diff. on every person, but just curious.
