What To Do If There Is Constant Pain, Cramping In The Calf Muscle And Cast Felt Tight After Fracturing The Fibula?

I have a spiral fracture in my right fibula, and am scheduled to have the cast removed this Wednesday. Called and left my doctor s office a message today, but no one has returned my call, and now the office is closed. On Friday, I had some swelling, the cast felt tight, and I attributed it to working a full day and not having the leg up at all that day. When I got home and was able to put the leg up again, I experienced painful cramping in the calf muscle. It has hurt since then, constant feeling of cramping and very sore all the time. I need to know if this is something I should be worried about and address immediately, or if I will be ok until I see the doctor on Wednesday morning.
