Has anyone else experienced muscle cramps all over the body on prednisone and entocort? I have been on entocort a week and pred for about 8 weeks and sometimes I have muscle cramps in the stomach area and today one leg felt like dead weight and the other my achilles was aching and stiff. I have had some weird pains like these on and off almost everyday since about 4 weeks on prednisone. Sometimes my muscles just seem to knot up if I stay in one position too long. I had swelling in my joints before but this is different.
