<s>[INST] I have a possible stress fracture in the base of my 3rd toe. MRI and X-ray showed stress reaction. I don t know if that means full stress fracture. I ran a marathon last week and it is actually feeling Okay. I saw the Dr. yesterday and he sayss that I need to rest it if it is ever going to heal. He said that he could put me in a hard sandal or I could just wear my shoes with orthodics. I prefer not to use the sandal. I teach P. E. and I am on my feet all day. How long will I need to back off from running. I also teach spinning classes and assume that I can continue to do this. [/INST] Hi, Your doctor is right. You have to rest your leg, it will take a couple of weeks to one month for complete recovery. Hope I have answered your query. Let me know if I can assist you further.
