I broke my wrists last year skateboarding and after the cast it was still a bit painful especially on my right wrist.
I tried magnesium oil, k2... a lot of things. I finally tried comfrey balm and it did reduce my pain a lot.
If I had known, I would have applied it directly just after my "crash"
This winter my ex gf had very dry hands all the winter until she tried comfrey balm, it was way better after. Beat all the bs dry hands cream she used
