I've started developing pain in my thumbs, esp left, when riding which seems to be aggrevated by shifting. Admittedly, a SRAM front shifter and interrupted cable set up doesnt help..
The pain is in the joint with my hand and the fleshy/muscle bit at the base of the thumb. With some mild discomfort in the first joint in my thumbs. There's no redness or swelling.
Obviously this is something to ask a GP, but I wondered if anyone else here has had similar issues. I'm 40 and may be prone to athritis as I have Crohn's Disease, but hopefully it isnt this.
ps - please dont tell me to MTFU and, no, grip shifters arent acceptable!
