Bumps where there shouldn't be bumps-(7 posts)

Has anyone developed bumps at the base of their thumbs?

Just this morning I noticed a lump under my skin (not a callouse) on the inside of my thumb, at the base, just before the webby part. It's about 5mm in diameter and feels about 3mm high. It's not as hard as bone, but not squishy, either.

There's one forming on my right thumb too.

Time for new gloves, eh?

for a visit to the doc. i don't wear gloves unless i'm racing and i have never had anything like you describe. maybe your position is a bit off as well. i have callouses on the heels of my hands from riding because that's where my weight rests. get your position checked by a GOOD shop that actually knows a bit about it! there are many that don't!

Yeah, probably nothing but I would have a Doctor take a look at it.

I'm trying to imagine how you get presuure there. It seems like this would be pressured if you have your hands on the (brake) hoods a lot, yes?

I'm usually behind someone, so my hands are never far from the brakes. My palm is mostly on the curved part of the bar - so, not technically on the hoods. I never ride in the drops.

I do have callouses on the skin over the bumps, so it's certainly a well used pressure point.

Seems like I remember a physiology class talking about some people developing these types of things on the bottom of their heel bones from, blah, blah, blah...that's as far as my memory stretches! :)

Musta been snoozing that afternoon-

I may just have an odd grip - my index fingers are almost as dark as the 'little circle' on the back of my hand. My thumbs are a close second.

You are not the only one with bumps and callouses. I have callouses on my middle fingers from gripping my hoods when climbing out of the saddle. I never noticed them until my girlfriend pointed them out.

You could set up a booth at big bike events and advertise yourself as a bike psychic who can tell by looking at your hands whether or not you use campy or shimano.
