Has anyone experienced this? I am on day 10 of 40 mg of prednisone and when I have to go it his like a brick and I have to go now. There is not much room for waiting.. I have been going a lot since starting the prednisone. I am retaining some fluid, craving salty foods and getting headaches, chest pain etc. I was fine before I knew I had a problem. If I look back at it I had some symptoms but thought it was cause of being out of shape. Anyway, Help please..
