I was away for a week in sunny north Norfolk last week. I had hoped that the problem would clear up with the rest. Nope!
Now, I've been prescribed some special gel to rub into my thumb and I've been given this splint to wear.
I feel decidedly Darth Vader-ish or Luke Skywalker-y! I've been told it should sort itself out in a couple of weeks. Interestingly, the most effective thing has been alternating the hand between bowls of warm and cold water. A minute in each and swap five or seven times, starting and finishing on warm!
The tendon in the thumb is inflamed and any strain will exacerbate the problem...
...I can type and drive a mouse, but pen-work has been nigh-on impossible. It's a worry, but hopefully, it should clear up in time for me to start the next episode of Banned Across the Universe!
