Hang in there. I have been weight bearing and using a cane for about three weeks after 15 weeks in a wheelchair. I have the same aches and pains, but I have found this helps:
Heat in AM to loosen up the muscles and tendons. Ice in PM to help swelling and pain.
By the way, my physical therapists explained that foot and ankle pain as being caused by using it after a long period of non/limited use. Think of it as the tendons and muscles having an extended vacation on a beach, and on day one back to work they are required to go put in a 20 hour shift. They are not happy.
Again, keep hanging on.
