Persistent Itching and redness in breast

If it were me, I would check in with my doctor. Are you getting regular mammograms?

@ebenfash
That maybe a cause for concern.
Go get a mammogram.

@ebenfash Welcome to Mayo Clinic Connect.

My advice is to get to a doctor right away! You want to make sure this is not something serious.

Yes, call your doctor for an appointment..
Next check the things you were using lotions, perfumes, deodorant anything that touches your skin as well as laundry soap if you use a softener see if any of them have made changes to their products..
Did you get a new bra? Is it tight or constricting that might be some of the issues like sweating?
I wish you the very best and good luck finding the answer

This could just be a skin dermatitis, either from sweat or secretions, fungus, bacteria, reaction to some kind of allergen that is new to your immune system....or it could be an indication of underlying pathology, including the dreaded 'C.' I agree with the previous kind responders....this should not be delayed and it needs attention, pronto.

I hope you can manage to be optimistic until you learn what it is....and even beyond. One famous sports physician said, 'When you hear hoofbeats, think of horses, not zebras.' This could be as easily treated as applying a cortisone cream.

Agree with the previous post regarding some type of dermatitis. It's important to maintain the tissues below the breasts clean and dry. Use of antifungals should clear up the infection after three weeks... with twice daily treatments. Once the skin heals, use of corn starch on clean / dry tissues may prevent the return of the rash.

All the best!

did you get a new foam mattress? I had this reaction when I purchased new foam mattress.......so now I have 2 mattress pads and 2 sheets between me and my mattress.....solved my itching and redness, I also had this kind of reaction when I bought new bra which had foam liner.....

...oh, and laundry detergent, new clothing, clothing that you like and want to hang onto, but it needs a deep cleaning, maybe a soak in an anti-bacterial solution for an hour or more. It could be isopropyl alcohol, 70% from drug store shelves, or a small bit of bleach in a liter of the soaking solution, maybe a full tbsp. I dunno if we're helping with all this guessing, but any one of these might be 'it'.

All interesting possibilities but I strongly suggest you get into see your doctor for a diagnosis and treatment plan.

Put a liner between the bra- such as cotton strips or even paper towels folded over. Works for every fold.
