I used to get those in both both thumbs. They only lasted 2 months for me. I felt like the shots were affecting my wrists and when Covid hit and I couldn't get in to get them I quit. At night I use Lidocaine or Voltoran or icing for some relief. Certain chores are really difficult. Fencing, wrenching and the like. The other day it took me 15 minutes to tie a blood knot.
