Pin point red dots tight clothing

[Emilyy1547]

Anytime I get very stressed or wear tight fitting jeans for a long period of time I always seem to get these pin point red dots on my inner thighs by my vagina. They disappear by the next day. Just very confused on if this is an outbreak or not every time because there is no way they would disappear by the next day. Just wondering if anybody else has ever had this issue

That's almost certainly a friction rash.
