bump on thumb. [View all]

This is a pic of it...



It began a week ago while gardening. I didn't notice at the moment that anything happened. I'd been clipping back an Artichoke bush. At first I thought it was a blood blister. Today it started hurting more. And I see a black dot in the middle of it. Preparing a meal is painful.

It seems such a tiny issue to bother a doctor about or go to urgent care. I'm trying soaking it in hot water to see if something can be drawn out, like a splinter.

Anybody experience this or know what it is?
