my foot almost heals after 8 weeks in a cast however im disabled (veteran paratrooper with fallen arches) and from a lack of exercise morbidly obese 350 lbs so can a person be in a cast for more than the 8 weeks allotted for this injury i told my dr it wasn't healed he said you cant keep that cast on forever it sucks being in one but its working if it can stay on long enough is there much harm in casting it for a longer period atrophy can be taken care of with therapy right? this has been going on for a year now off and on more on though ty Richard
