I ended up falling and breaking my fifth metatarsal. I went to the ER and they put me in a temporary non-weight bearing cast. Everything was fine until that same night I got a burning sensation on my heel. I was in so much pain. I read that it maybe cause by swelling so I tried elevating my foot. That works for about 2 to 3 hours and I'm woken up to the same excruciating pain. Please help!?
