It doesn’t sound like anything sinister to me and if it was me I’d totally be making it worse by touching and checking all the time!I think I'm just panicking because its been there a few weeks and I'd hoped it would go away. Thank you for this reassurance, it doesn't help that when you google things like this it just flags up all the horrible things it could be and it just sets me off down a rabbit hole and fearing the worst. I always forget how sensitive our skin there can be. I will keep a wee eye on it but try to leave it be. I am glad everything was ok for you, its so stressful just wondering x
Earlier after a shower I did poke around with it a bit more to see if I could feel a lump or if it was painful and that is potentially what is causing it to be a bit purple/bruise like in the middle. Keeping looking at it just willing it to go away but I will keep an eye on it and fingers crossed.
I’ve also done a Google look for you (I always get someone else to Google for me as I only see the bad stuff when it’s myself) and honestly nothing is really coming up they should make you worried. Some really rare breast cancer but the rash would need to be much bigger and there would also be other signs. Sounds like it’s a rash / heat / allergy etc.
