Does this rash look like the start of mastitis?

[LauraP94]

It feels sore/bruised underneath and is hot to touch. It's been sore since this morning but I only noticed the rash a few hours ago.

There's no picture
Is it just under 1 breast?

It was pending approval but is there now. Yes just one breast.

I am a breastfeeding supporter, and I would say yes, it could be. Have you got fever? How are you feeling? Try and give a call to the National Breastfeeding Helpline. They are on 24/7 and they can advise you!

No fever and I feel ok. Good idea to call the helpline - thanks.
