Why is my thumb swelling for no reason?

Hi, I'm 13. When I was laying down on my bed, my thumb started to feel weird. It wasn't in any weird position, but I realized the feeling was it swelling out of nowhere. The skin got tinder and tingly and soon started to feel kind of warm. It all happened out of nowhere and at once. I also noticed a small shiny bump on the fold of the middle and upper section of my thumb. Imagine a small pustule with a black dot in the center. I don't think it was a pustule though. I'm a little concerned about this and nothing I looked up was talking about this. Someone please help me figure out what this is.

Your question only came up on the Paediatrician's question today (6 May)

The most likely cause of swelling and tingling of your thumb is an infection. Based on your description of noticing a small pustule with a dark spot in the centre, the most likely possibility is a splinter or possibly a prick due to a thorn such as a rose thorn. Infection is the most likely cause, but another less likely cause is that this is due to gout. Gout can start for the first time in the thumbs although the big toe is more likely. If your thumb is still swollen and painful, you must see a doctor. If this is due to infection, you will need an antibiotic.
