Looking for some reassurance. I've had a very itchy right armpit the last few days. I haven't been using any new soaps/deodorant/detergent so I'm not sure what's causing it. There's no rash that I can see. Now I can feel a slight swelling under the skin so I'm getting worried it might be something serious - I've googled possible causes and inflammatory breast cancer is one. No changes in breasts that I've noticed from a check. I will phone GP on Monday but in the meantime I'm looking for some reassurance that it's likely nothing. Perhaps someone here has had a similar experience? Thanks.
