Can prednisone cause blurred vision and numbness in feet?

The only thing I cannot leave is the prednisone. As soon as I try to quit I go into bad pain and immobility again so I keep up with it and take the injection. I did gain a lot of weight but I don't care about it anymore. I can move and I can do my things without help and I love that ;so who cares I am fat. On my first year with this illness I was almost an invalid. Had to cut my hair because I could not raise my arms very well to comb myself. My husband did not know how to do anything with my long hair. There is hope, do not despair. Looks bad in the beginning but you get better with time. The blurred vision and the numbness on your feet could be diabetes. Check with your doctor. My rheumatologist told me to go on a diet as soon as I started prednisone, she said that it can raise your sugar and cause diabetes if you don't eat well. I know my sugar went up in the coming years but still not enough to be diabetic.
