Off knitting

Before Christmas, my lovely daughter was dancing with me and swung her full weight on my right thumb. I thought little of it at the time, just carried on with the day.
A month or so later I realised that the thumb was still aching on and off. One trip to the doctor later and I have come away with a diagnosis of tendonitis in the thumb. Apparently quite a common injury, but can go on a while. I’m under instructions to rest it, and treat with ibuprofen and heat.
It turns out that I use my right thumb for… everything. Getting dressed, cutting food, writing, typing, lifting, turning, shaking hands and, of course, knitting, spinning and crochet.
I have a feeling that crochet doesn’t use it as much as the others do, so hopefully I’ll be back to that before too long.
Anyone want to take a guess how long it is until I start to crack under the strain of being without my destressing mechanism?
