I think it may be because the underwear is too tight and the leg hair is embedded in the gap of the underwear. When you walk, your leg hair will be pulled off by your underwear, so you will feel pricked. If you turn your underwear over, will you find short hair piece by piece? As for little red dot, you may be allergic to the material of underwear, and I sometimes do, as long as I don't wear it for a few days. Besides, you said you don't sweat, so this kind of dry skin is also related. It is recommended to drink plenty of water after bathing and apply skin cream all over your body. Ordinary dabao is very easy to use

In addition, it is recommended not to wear thermal underwear with hair on the back, which is particularly airtight and tight. I wore it once and never wore it again. It feels good to wear ordinary cotton underwear now. If you are afraid of the cold, buy thick clothes and wear woolen pants.

These are all my experiences, and I hope I can help you. Hmm. How interesting
