Answer:
If it is just in one spot, where the button or belt is touching your skin, it might be that you’re allergic to nickel / metal….. I’ve to be careful, it starts with a sort of reddish irritation but if I don't change trousers or belt, it gets really sore and hideous. Alternatively, did you change washing powder? It might be that this new detergent does not agree with you…

Answer:
they could be getting two tight.

you could also be having some sort of reaction to a new washing powder you are using, or they just need washing in general.

cut off bits that are itchy (like lose bits of thread if there are any) and things like that to make them more comfortable.
