What is the best treatment for a broken left foot m#5, it is 1mth old break, i am in an airboot cast, with no relief & am still in pain? please help!

Re-evaluation: You need get evaluated by a doctor to determine if the bones are healing properly.

Fractured foot: Im assuming m#5 is the 5th metatarsal. Fractures of this metatarsal vary drastically...Metatarsal head, shaft and base fractures are all treated differently...Some can use an airboot ( which cannot be removed or fracture will rebreak ), non weight bearing casts, and surgery with fixation. Since, yours is a month old, and you are still in pain, i would recommend you see a specialist very soon.
