Most people have no side effects from Cortifoam because the amount that's absorbed is relatively small. For some people who are especially sensitive to steroids, though, side effects can be a problem.
Muscle cramps and insomnia, of course, are classic short-term side effects of oral steroids. They're not dangerous, just annoying, and often we choose them over the pain and debilitation of the flare. Making sure you get plenty of potassium will usually take care of the muscle cramps. Have a glass of orange juice or a banana for a snack; they're high in potassium. If the insomnia is due to steroids, it may pass after a couple of weeks.
You needn't be afraid to use the Cortifoam, as I said, even if these are side effects to the steroid they are annoying but not dangerous. As someone else suggested, try experimenting with a smaller dose to find out if that will relieve the symptoms without causing you problems.
