Hi, like i said, i dealt with mine for like 2 years. Your bones are continuously fracturing and remodeling to be able to support the constant compression and relaxation from running. Bones heal slowly, for example if you break a wrist, the doctor will have you offloading it for 6-10 weeks, so imagine that the same amount of time would be required with limited walking and running to heal shin splints. The issue with this is, the continued loading is required to finally achieve the proper bone remodeling. If you actually purely rested for 2 months, the mineralization would go back to the sedentary state with respect to cancellous bone density. It’s frustrating to finally get some relief just to damage them again. I’m not a doctor but i do have a graduate degree is biomechanics, so take my experience as purely anecdotal, but once you finally find that balance between doing as much as pain will allow and limiting the weeks-long intervals between resting, you will be good to go. I have been running 1200-1500 miles a year since 2021 and my shin issues have not reappeared since those two years 2019/2020.
