Red circles under breast. I am overweight, could be sweat.  Hurts and itches.  How can I fix it?  Is it underwire bra, no bra, wrong size bra?  Powder sort of works by only for a bit. Smells.  I am 56.  I prefer underwire.  Perhaps Ive gained weight, my bras are uncomfortable.  I thank you, just want to know if its anything to worry about, and what I can do about it.
Hello! I have been through your question. Related your concern I think this could be yeast (Candidiasis) infection. Furthermore, you should know that when a rash is present in an area where skin on skin contact occurs, this is known as intertwine.  Intertwine is inflammation of the skin folds that is caused by increased moisture and friction in the areas where skin meets skin.  The area with intertwine can produce intense itching, burning sensations, and it may also have a terrible foul smell similar with your symptoms.  The inflamed skin under the breasts can be an open door for Candida.  What I suggest for you is to keep Chat Doctor.  Meanwhile, meet a doctor to start local antibiotic therapy. I hope my answer helps you. I wish you a quick recovery.
