Is severe pain common after a leg cast removal?

In December I twisted my foot and thought it was broken. After a trip to the emergency room, an orthopedic surgeon, and two x rays I was diagnosed with a severely sprained ankle and foot. I was given a walking boot and sent to physical therapy. After about a month and a half of no improvement my new doctor decided to get an MRI. It turned out that a bone in the middle of my foot was fractured and because I had been walking on it it was actually getting worse. They put me in a hard cast at the beginning of February and I was confined to a wheelchair and crutches. Last Friday they cut my cast off and put me back in the walking boot. The doctor said that I could walk when I have the boot on, but I physically can not put any weight on my foot. It feels like there is an ice pick being shoved up my heel. I can’t even stand on it. Is it common to have such pain after not walking for a long period of time?
