Sore under breast in crease

[insomniaclife]

What's the best thing to use to relieve or ideally do away with, the sore red area developing in the crease between breast and body? As I only very infrequently wear a bra, and sit a lot for work, and am aging, this area is suffering and I have no idea what to try.

Sudacreme?

It could be a fungal infection - try canestan cream (the athletes foot one).

Yes, I use Sudocrem - apply straight after washing and drying - always clears it quite quickly.

Yes it will be a fungal infection, it's known as intertrigo. You need an antifungal cream from the chemist. Go and talk to them

It could be a fungal thing, in which case Daktacort used sparingly.

Use the over the counter ( on Tesco shelves) atheletes foot cream there’s two strengths both work and improvement is almost immediate

As others have said it fungal , basically its a sweat rash .
I'm assuming you have big boobs , it's where they sweat where the skin touches each other . You say you don't wear a bra very often , that's not helping .
Try to air them as often as possible by lying down , keep that area as dry as possible ( medicated non talc powder ) during the day , and a suitable cream at night .

That's great advice and options thank you all (am off to the chemist now)

I get it occasionally in Summer/warm weather. I swear by Daktarin powder.

I have extremely large breasts unfortunately and sweat, red, sore weepy rashes is something I am more than familiar with and have been for decades. Talcum powder rubbed in and re-applied regularly works wonders.

I had this recently, first I tried sudocrem then hydrocortisone cream then thrush cream. The latter two did it.
Get some stretchy "sports bras" if you don't wear a bra.

I suffer from this and use my own hydrocortisone and Caneston athlete’s foot cream mix as recommended above. Works a treat. Make sure you try to wear cotton tops and bras is my advice.

Well you don't have to be familiar with it...get yourself some antifungal cream!
