Not sure what it is but scars

A photo added. Randomly I get skin lesions now for about 2 or 3 years. One at a time they pop up on my body, under my thighs, on my hips or breasts. They do leave a dark spot when they heal which frustrates me and are tender. I’ve tried changing soaps, shampoos, not using powder to using it, no tight clothes.
