Hello, and good morning! I have a rash that started on my armpit area, it is very ichy, red, area with very smallbumps that u can feel when u rub lightly., but can't really see. It is now on the sides of my breast, the bends in my arms and legs, also on t

Rash. This rash would likely need to be examined and more history obtained to be able to provide you with useful input about the diagnosis or possible treatment.
Hard . Hard to tell without a picture, but it is possibly dermatitis or eczema. Any chance it is a skin allergy? I would recommend you try a gentle hydrating cleanser such as cerave and use a moisturizing cream such as cetaphil or cerave twice daily. If not improved, consider a trip to a dermatologist for evaluation and treatment options. I hope that helps.
