Allergic to detergent?

Whenever I sweat or I get nervous the parts of my body covered by my clothes become super super itchy. It only occurs where the clothes are. Plus my face has these tiny bumps on the skin (not acne) and it feels dry and itchy even though I have a pretty oily skin tone. I've also got a case of acne on back plus a lot of redness (not from acne because the redness is everywhere on my upper back) and sometimes itchiness.
