The problem seems to be the adductor pollicis muscles, so it's both the grasping the bars and the pressure between thumb and finger that are the problem. Often even things that aren't especially painful at the time seem to aggravate the problem a few hours later. It's very hard to rest them completely. but I have been doing my best to adapt and avoid using the relevant muscles.
I can just about ride a flat bar e-bike for short distances by resting my hands on top of the bars but it's far from ideal for control and there is still some pressure on the base of my thumbs which I think is not helping recovery. Shifting down gears is awkward as I can't really use my thumb, but gripshift would be impossible! (Perhaps I should try a thumb shifter on top of the bar?) I wonder whether rotating the brake levers up to a flatter position would help with control.
Although I'm waiting for a physio appointment, based on GP visits and progress to date (there is possibly some joint instability that could be be a factor), I'm concerned that this may be a long-term problem and I'm trying to work out if there are any ways that I can still cycle without aggravating it.
I want to be able to cycle commute 25-36 mile round trip, and recreational riding for fitness, preferably keeping up with road bikes.
I've put some S-bend clip-on aero bars on the road bike, which I've tried on the turbo. It seems I have a lot of adapting to do to the different position and of course access to brakes and gears means I will have to use the normal position some of the time.
I'm also hoping to try some stubby bar ends for flat bars to see whether I can support my weight on the other side of my hands using these.
Are there any different kinds of handlebar I should look at?
In the long term I wonder whether I'll have to try a recumbent cycle of some type, but not sure what the handlebar arrangements are for these - I know there are many types.
Does anyone have any experience of this kind of injury, or suggestions for things to try please? There must be others with thumb problems who have wanted to cycle in the past?!
