How can I get rid of my body odor?

You may have a mild skin infection.

Try bathing the areas with a skin disinfectant (detol) normally used for bathing wounds. Dry thoroughly with a clean towel

you cant afford not to go to a doctor, theres progranns out there that help people that cant afford it, like sliding scales or whatever, ive had 5 surgeries and all without health insurance, its not innpossible, go talk to social services, they nnight be able to help you out with that
