  1. Nurse here, I have found a quick spritz of lotrimin miconazole spray under each breast is far less messy than a cream. If you have broken skin there it can sting at first, but usually after a few days it resolves and you are using it daily as a preventative. I’ve been using it for about 10 years, and the only time I develop any issues is when I am without it in a very humid environment, like when I’m traveling. I use the Miconazole powder when I travel, and it works, but it requires multiple day application to be effective. Obviously if the spray isnt working or seems to be making it worse you need to stop and reevaluate. But it’s easy-to-use, cooling and helps keep me dry and irritation free. In the past I tried all sorts of creams and powders (some mentioned here) and none worked as effectively as this spray. Its found in the foot section, check the active ingredient so that you are sure its Miconazole. And the generic is as effective for me as the brand name. Also keep bras washed and dried well, keep your weight down, and be aware that conditions like diabetes can make you more susceptible to yeast infections and infections in general.

  2. Rinsing the sweat from our body is key, i think because it prevents the bacteria to break the sweat and make that bad odor 😅. Also sweat is quite irritating. Thanks a lot doctor Andrea for the educational video 😊❤.

  3. As a lady who has had to deal with this problem every summer except for this past year, I have tried everything that has been recommended, and I can share with what works for me.
    1. Get yourself a properly fitted bra! Go for thin airy fabrics that are unlined, with a proper band support and cup size. Basically, go for the comfortable and supportive bra design that separates the bottom breast skin from rib cage skin. This is the reason why I go for the ‘minimizer bras’ over ‘sports bras’ for working out. I have found it easier to run in minimizer bras than a sports bra. Bralettes are a No for me, because these loose bra bands allow for skin folds and trap sweat. If you know, you know.
    2. Change out to a clean/dry bra after you’ve sweat in them.
    3. Benzoyl peroxide cleanser for rash. And use hypocholous acid spray as maintenance, let it dry and put on a clean/dry bra.
    Good luck!

  4. Such a helpful video. I was misdiagnosed for a long time. Finally got it right and it cleared up immediately (clotrimizole and hydrocortisone crème)!

  5. When I start to get an under breast rash, I find applying some Panoxyl while in the shower for a few days in a row works

  6. As an H cup gal living in the swamp known as Houston, the absolute best thing I’ve used is the Monistat chafing cream you mentioned. I also used to use it as a face primer 😅

  7. A good friend of mine recently revealed that she hadn’t had her bra size remeasured for more than 30 years! She visited the foundation garment section at a department store where the very experienced fitter/saleswoman let her know that the 12C she wore in the 90s was no longer the correct fit for her 14DD bust in 2024. Unsurprisingly she’s now a lot happier in her underwear 😁

  8. Never had this problem, but I agree with the comments about getting a bra that fits and supports. Because of being a runner, I always just went with sports bras, literally my whole life. About two years ago I realized how unflattering sports bras are and how they don’t fit too well (S/M/L is oversimplified for bras). I got a Playtex 18 hour wire free bra in my correct actual size, and what a HUGE difference. My shoulder pain stopped. I felt so much more comfortable. Never had this rash though. It sounds terrible.

    Don’t just be thankful for what you have, thank God for what you DON’T have that you DIDN’T want!

  9. Some thing as simple as a absorbent paper towel folded and placed under the affected area can keep that area dry enough in the summer to stop the breakout.

  10. I’ve never dealt with this but I’m fairly small chested so maybe that’s why. It looks incredibly painful! I can’t begin to imagine how miserable this is. Especially in the hot, Summer months. I know this video will be helpful to many. You’re the best, Dr Dray! Happy Tuesday!! I hope you have a peaceful evening. 💖

  11. I had this for several months a while back. There were open cuts where the skin had broken down. Showed my PCP on a visit and she told me to soak towels in vinegar and apply for as long as I could tolerate daily. I like your ideas so much better! Now I use Panoxyl in the shower and powder, and occasionally hypochlorous acid.

  12. Glad she mentioned psoriasis! My first psoriasis lesion showed up under my right boob at age 25 and looked like a huge spider bite and itched LIKE MAD. Was misdiagnosed for almost 20 years until I was diagnosed with psoriatic arthritis.

  13. Hi Dr Dray, I had my annual dermatologist visit today. I have KP on my arms, and had noticed that I’d started having bumps on my chest recently. I work out alot, so I began using a benzoyl peroxide wash after workouts to try and clear it up (thinking it was mild acne). It wasn’t really helping and eventually after trying salicylic acid too, k began to think it could be fungal. I occasionally use Head and Shoulders for my scalp and itchy ears so tried it on my chest but still wasn’t sure what the cause of the bumps were. LONG STORY short, after relating it to my dermatologist, he was impressed I’d thought to use the Head and Shoulders. He was fairly certainly was Malassezia folliculitis, which you’ve covered before, and now I have a prescription for an oral medication. Thanks for making me look so smart!! Love your channel!

  14. I bought bamboo liners under my breasts in the Summer. They really help to keep the area dry. Made all the difference in the world!
