What is the reason for the round blister at the base of the thumb

Reason 1, may be sweat herpes or eczema, which is a skin allergic reaction.

Second, it may be infected with tinea manus, a fungal infection caused by hand disease.

The third reason is that the palms (including the soles of feet) only have sweat gland pores (lack of pores), and the skin is thicker (the passage is longer), so the ability of metabolites (the main liquid) to pass through the palms sweat gland pores is relatively weak. Once the skin invades into the water, the water adsorption force is enough to block the sweat gland pores. In this case, there will be metabolites in the subcutaneous tissue of the hand, which will accumulate in the palms And formed bubbles.
