What could be causing this red line between my breasts?

If your camis are also causing the skin in that area to pinch together, they could also be causing it. Also, having your skin constantly irritated for several years could be causing it to be more sensitive. Have you tried going without the camis for a while to see what happens?

Have you tried hydrocortisone cream? It’s available over the counter, and suppresses the immune system response, which is what generally causes the reddening where the skin is irritated.

Buy some cortizone cream in the drugstore and put it on twice a day for 4 days and see if it reduces the redness. I usually buy Cortizone-10 brand, comes in a red and white tube. Don’t get the one with fancy menthol or cooling. Get the cream, because the ointment will be greasy, and geton your clothes. Don’t use it longer than a week. If it shows not improvement then ditch the idea.

Next you must go and get measured for a bra and fitted into a good quality one. Wacoal is the best. Cheap bras will cut into you, and if you are wearing them too tight or too loose it is a problem. You are still wearing your bras during the day, so if it is irritating you, that is a good 14 hours of irritation. Nordstroms and specialty lingerie stores should know how to measure. If you want to measure yourself, take a meauring tape and measure around where the bra goes around your back, just below your breasts. Add 4 for most quality bras, like the Wacoal I mentioned. So if you measure 30, you are a 34 bra. Some less expensive bras add 5.

The other possibility is it could be a yeast infection, but I would think your derm would have diagnosed that? Still, if you want to try everything, with little down side, you could buy yeast infection cream, even the GYN stuff will work, and apply to the area for a few days. Make sure to keep the area dry. If you tend to sweat there that might be aggravating the problem.

When I said next get measured for a bra, I did not mean after trying the cortizone cream, I mean do both right away.

Have you been professionally fitted for a bra? Based on your description, I imagine that you’re large-chested and that your bras and camis are pushing your breasts together. A properly-fitting bra shouldn’t do that, regardless of how large your breasts are.

I would think that wearing tight camis would also push your breasts together, creating that crease. Over time, it’s quite possible that a red mark would appear there. Like @JLeslie suggested, it could also be a yeast infection, or just irritation stemming from that hot, sweaty little area. I would strongly suggest wearing looser clothing to bed – if you feel you need to rein in the girls during the day, so be it, but they ought to roam free at night regardless of size.

Most Victoria Secret bras suck by the way. On the off chance you wear their bras. I worked for Calvin Klein and Wacoal bras, and there is a real difference.

Yep, I vote for prolonged irritation, and maybe, you have an allergy to latex. If the elastic edges of your bra are latex that could be something else to consider.

Yes @Seelix breasts need a lot of free range time. Don’t fence them in, they will rebel. lol

I actually wear MaidenForm bras that I buy from Kohl’s. I don’t really have the money for a higher end bra, but I’ll do what needs to be done. And no, I’m actually not large-chested at all. haha. I wear bras with padding/push-up to create the illusion that I have more than a small B. :)

I was actually going to say that many large breasted women wear some sort of “bra” to sleep, and it is not a bad thing, because gravity pulls on their breasts and once you damage the tissue in the breaSts, not the muscle behind the breast, but other tissues, there is no way to exercise those other tissues back into shape. But, now that I know you are a B, which is a wonderful size to be by the way, you don’t have this worry. B can be made bigger with some padding or push up, but can go braless without concern for the breast during inactivity.

Most people wear their bra too loose. For instance, most people walking around wearing a 36 B are actually 34 C’s. Wearing that larger back size means the bra moves around, usually causing the straps to fall off the shoulders, and can rub below the breasts and inbetween. There is a percentage of women who wear the backside to small, and that obviously puts pressure on the skin.

If your bras are old, they may have stretched and become too large.

I’m sorry, but I’m gonna need a recent picture if I’m to make an informed diagnosis…

@stratman37

hahahaha, very good!
But of course, one cannot reliably diagnose something they cannot see and feel.

I’ll never need any of this info, but it gives me new insight into what women have to deal with. I’m also impressed—as always—by the wealth of knowledge and experience jellies share.

Oh, and thanks for the giggle, @stratman37.

I would have guessed a yeast infection, also. How long ago did you see the dermatologist?

I saw the dermatologist a month ago, but the line has been there for over a year. If it was a yeast infection, wouldn’t it have gotten worse or spread by now?

@lbwhite89 Not necessarily. I was thinking to tell you Lotrimin cream will treat yeast and will be cheaper than buying it in the feminine section (I mention the GYN stuff is the same in case you have some at home already. Well, Lotrimin has the active ingredient clotrimazole, some GYN products have a different antifungal). You can find Lotrimi near the foot section. It’s worth a try I think, if the cortizone doesn’t cure it. And, maybe don’t wear a bra for a week if you live in a cold place and can wear sweatshirts no one will probably know. This weekend is a three day weekend, maybe at least for the weekend?

Also, in the summer were you in a bathing suit everday? Not wearing you bra as much?

Lastly, if your bras are lacey or a rough material, try to only wear your bras that are very very comfortable. I used to always tell women the ugliest bras make the prettiest clothing.

It sounds like a plain old crease caused by your breasts being squished together. The camis might be doing it a little while you sleep, but I’d bet that you sleep on your side at least part of the time, and that one breast is simply falling or leaning down onto the other one and creating a crease which appears as a red line.

@Anemone Yeah, that’s why I think she should not wear a bra for a few days, you explained it better. If she sleeps on her side so there is a mark, and then puts her bra on immediately during the day, it could be like wearing tight pants all the time and always having red mark around your waist.

I have this too. I also sleep in a bra and Cami most nights and now during the day also. I feel like that’s the common cause, I was beginning to worry to. Thanks for posting this!
