oh yes, the sternum.
(didn't know it was called breastbone! oops)
yes, I had pain, a lot of cramping, churning pain at the bottom part of the breastbone.
I was saying stomach, but that's a good description too.
so bad wearing a bra was out of question
I really think it's gallstones. loads of people have them and in my head it is the most likely scenario, based on your symptoms.
it does come and go
I had 3 gallstone attacks, last one was when I got jaundiced. horrible.
please get seen asap, if your gb is inflammed ora stone moves you could end up with pancreatitis which is very serious.
and don't let them shrug you off. pester pester pester.
squeaky wheel gets the grease.
next time you are in a lot of pain, especially if you are vomiting call an ambulance. so it's on record that you were admitted. it will speed things up
(and I wouldn't normally suggest to drain NHS resources but when it happened the first time I was pg, and when it happened the last time I was really ill and our surgeon friend said having a medical history recorded will make a big difference in how quickly you can push things.)
