I rock climb regularly and a few years ago I started feeling a stinging pain in my hand, under the skin. It didn't feel muscular, more like a pinching, or sore spot. I kept climbing despite the annoyance and once day while climbing there was intense pain from the spot and dark reddish/purple spots formed under the skin in the area.
Now, a few years later, I still feel pinching/stinging pain in the area when not being touched, and especially when there's friction on that spot of my hand. Sometimes there's some reddish under the surface of the skin, but it hasn't burst like it did before with the dark red spots.
I'm still trying to figure out what this might be, a burst blood vessel? Or something else? It's been 2 years and it still hasn't healed and I'm not sure what to do. And I'm worried if the damage is permanent.
Thank you for any and all insight.
