Small red raised dot on thumb, heavy bleeding?

Hi, after climbing the highest mountain on Vietnam over two days (may not be applicable to the diagnosis) a small red dot appeared on my thumb and over a couple of weeks began to raise slightly. I assumed it was a small splinter or grain of dirt trapped under the skin, but when investigating with a needle I could find nothing solid and the small sand grain sized thing in the middle of the 'tiny volcano' shaped bump began bleeding profusely when jabbed. Since then the bleeding has stopped and it now looked like a tiny, recently erupted volcano, possible what I see in the middle is a cluster of blood vessels and not something beneath the skin but it still feels hard and raised and a small circle of skin around it has turned white, I guess due to lack of blood. Any ideas whatsoever?

Hello and welcome to ehealth forum.

It could have been an infected boil. There can be significant bleeding , if the area is infected and in a vascular place such as the pulp of the thumb. Apply povidone and neosporin topically. With the mountain climbing history, tetanus toxoid booster should also be administered. The would should be examined and if required oral antibiotics can be advised.

I hope this helps and wish you good luck
