PredniSONE and five months

I have been on prednisone taper for about five months, starting at 40 mg for six weeks, and then tapering to 30 mg for six weeks, 20 for six weeks, and I am now down to 15 mg for macrodantin induced pulmonary fibrosis. I have had weight gain, bloating moon face, muscle cramping, hair loss, and mood swings. I will be glad to get off this drug, although it has helped me a lot. I also have hypersensitivity pneumonitis, and it does not help much for that. I will just have to move out of the area because I am very allergic to something and cannot find out what it is. The water retention and the moof face are the hardest to take. I also have had back pain since being on this, and I don't know for sure this is a side effect or not. I have heard of others who have had this and when they stopped the prednisone, their back pain went away. I will let you know when I am off in April.
