side effects

I had a short course of prednisolone for 5 days then rhinocort nasal spray fr 6 days then prednisolone 50mgs and25mgs for 2 days I was told by DR. to stop due to side effects.I have painful legs ,back and my legs get so tired and weak when I walk. I went to see a Doctor who seemed surprised it was a side effect and said it would go away.Will thes side effects go away its been 6 days and I was not on the drug that long.I WOULD BE SO HAPPY TO RECEIVE ANY ADVICE, S.
