Methylpred DP and leg cramps

After taking this medication for about a week, I have been experiencing severe upset stomach, tiredness and severe, severe leg cramps in my calfs during the middle of the night that cause me to "try" to stand up and walk them off.

Recently I was diagnosed with severe bronchitis and head congestion, horrible cough and went to the doctor. My doctor put me on methylpredisolone.

Ever since I began taking it I wake up each night with severe leg cramps in my calf to where I have to get out of bed and attempt to walk and damn does it hurt. Is this a common side effect. I can't stand it.
