Back in October last year i was having really bad pain behind my eyes - they hurt on movement. I went to my doctors 8 times within two weeks - he kept giving me pain killers saying it was a tension headache. The last appointment i had with him id lost the vision in my right eye - they eventually referred me to the hospital. After loads of tests and questions they finally put me on Steroids and strong antibiotics via drip and i had MRI scans but by then i had lost my sight completed and was told i would never regain my sight as my nerves were severely damage. After a week or so on Prednisone my sight was getting slightly better in the left eye which was great i could think about seeing my son again. I have been taking Prednisone along with loads of other tables one for my bones and nerves and folic acid and very strong painkillers etc for months. I tried to reduce my dose as directed and my condition got worse the pain behind my eyes came back and they they said i had C.R.I.O.N so now im back on a high dose and im also taking azathioprine. I have experienced all the side affects of this drug - Round Face (moon face) server muscle cramp - i was unable to walk for 8 hours a few weeks ago i was in so much pain. Terrible bad back - shoulder blades hurts. Terrible spots. Really bad heaches. Eye pain. Water retention. Sleeping problems. Mood swings. Theres to many to list. This drug helped me regain my sight but i cant wait for the azathioprine to get into my system so i can start to reduce the steroid and start loosing some weight and get rid of all the other side affects.
