I have pain in the base of my thumb and “trigger” thumb that has required steroid injections over the past two years. I have been told that cycling and holding the bars can aggravate this and that it’s a recognized cycling injury. I ride about 4,000 miles a year. I also cross country ski, and gripping the poles can be aggravating as well. I have carbon fiber handlebars and use Fizi’k gel under Fizi’k’s thickest bar tape. Is there anything else I could do to help prevent this from recurring? Thank you. -- Jim F.
I have a similar injury to yours -- a "gamekeeper thumb" with badly stretched ligaments from college football many years ago, and aggravated by a fall while backcountry skiing in my area of western Colorado. So I can identify with your problem.
I have tried various remedies to alleviate the chronic pain while riding and also using poles for snowshoeing. None of them has worked perfectly, but they may give you some ideas.
In short, nothing seems to help in the long term. I notice the pain more when braking a lot on twisting mountain descents or hiking on snowshoes uphill for long periods when I'm using the poles for additional leverage.
I have been advised that I should have surgery done but that it might not work well since the initial injury occurred many years ago. So I use ice after rides that make it flare up and just live with it the rest of the time.
I hope this helps, at least somewhat, and I'm sorry that I don't have a quick fix for what sounds like the same gimpy thumb that I have.
