Why do I look like I've had a dodgy boob job on one side?

[IShallCallYouSquishy]

I woke up this morning with my right boob rock hard, painful and a bit lumpy looking. It was the one i had last fed from and massive compared to the left which hadn't been used since DD's bedtime feed.

It was so big and painful I expressed 5oz from it before her 2nd feed of the day was due but it's still sore and I can feel a harder spot under the skin, not the areola but the top of my breast.

Any ideas? I don't feel unwell or anything and nipple isn't sore?

Sounds like a blocked milk duct.
Follow advice from this link to mastitis to clear it

Mainly, feed feed feed & warm compress (filling disposable nappy with warm water & putting on your breast)

Thank you Bun reading that sounds like a blocked duct. Going to keep massaging and put warm flannel on it.
