Calcaneuos bone fracture

I was wondering if anyone has ever had a broken heel…..my specialist says it will be 12-18 months before I can walk but its been 2 months now and I can hobble about a bit….this week he told me to do my best to walk on it without a limp….very painful and impossible for me now but was hoping someone could tell me some exercises that may help with range of motion as well as how to massage it to the best benefit to help loosen up the movement so walking can be better. My doctor mentioned massaging it but its difficult for me to do that myself -= would one go to a massage therapist or who would offer this type of service? any suggestions will be greatly appreciated…….thanks
