I Broke My 5th Metatarsal Bone In Jan. 2016 Went

I broke my 5th metatarsal bone in Jan. 2016 went to ortho, they put me in a walking boot, had x-rays on March 17 he released me to therapy because of pain still in foot. I have not gone to therapy yet because of the pain and swelling. Was doing foot range of motion exercises and now my foot hurts again and have burning feeling along outside of foot and now it is swelling. I do not know what to do or where to go.
