Trigger Thumb

When my DR told me I have trigger thumb (which she demonstrated by gently pressing on the 'irritation lump' at the base of my thumb) we discussed options
.
A cortisone shot MAY help (doesn't help everyone) and would last AT MOST 3 months... and might or might not make the lump go totally away... meaning another shot
.
So I'm doing the 'non-intrusive' option of wearing a thumb brace... on in the morning and off on my way to bed (only removing during the day to wash my hands) for some unknown amount of time of at least a month, and maybe longer (with, of course, no guarantee the brace will fix the problem)
.
Typing is a bit awkward since the brace keeps hitting the space bar, but I'm hoping that keeping my thumb straight will, eventually, make the irritation lump and pain go away
.
This getting old and wearing out is not fun
