We had a Death Ride participant last year who got it and wasn't able to do a lot of the rides. He ended up coming out and doing a couple passes, which was good. And he signed up again for this year, so he must have gotten it under control. I will ask him about it when we start training.

Is it an auto-immune thing? Didn't you have Hashimotos before your thyca? I know auto-immune things can tend to multiply - which is why I'm a bit hyper-aware of auto immune stuff, having hashi's myself. (And now terrified I will get frozen shoulder, which is an auto immune thing, with this stupid fracture.)
