The itchy armpit is very irritating and disturbing.
The underarm itchiness is accompanied by irksome sensations like tingling, tickling, or prickling which can make you pick and scratch the armpit. It is quite embarrassing for you to do such things in public.
It is not a serious health issue. People in any age group can get a tickle in the armpit for many reasons.
However, persistent itching and prickling in the underarm region can develop into severe dermatological conditions depending on the reasons for it.
The armpit region of our body is both unique and delicate for many reasons. It is more than a few folds of skin and strands of hair. The armpit contains a large number of sweat glands, lymph nodes, and blood vessels.
The presence of numerous blood vessels in the underarm region makes this region warmer than other external parts of the body. A large number of sweat glands are present in the armpit to keep it damp and resist the excess warmth.
The combination of warmth and dampness makes this part of the body prone to various dermatological conditions which cause itching and tickling.
