Replying to Major Shin-bang issues

I suffer with some super bad shin bang issues that get to the point of unbearable pain where I cannot even walk. Doctor has told me I have to take it easy due to the high chance of my shin bang turning into stress fractures. This happens to me every year and always cuts my season short. I have tried literally everything. I got some full tilts- didn’t work. Went to a boot fitter and got shims and a foot bed - didn’t work. Got booster straps- didn’t work. I even tried various exercises and stretches- didn’t work. I’ve also tried things like different socks and wearing double socks- didn’t work. Yes I put my boots on correctly and yes I have tried different boots. Literally nothing works. I think it has to do with how I’m built - 6ft, 140lb, long skinny legs. I have no idea what else to even try. Let me know some things you guys have done or know can help severe shin bang like this.
