To cut a long story short, I was locked out of my flat, gained entry by climbing through a small panel above the door, and ran up the stairs, and felt a click from my rib.
The pain started two hours later, having been sitting at my desk. I have broken a rib before, and it was immediately obvious what had happened.
No problems breathing, and in fact I tackled a big hill the next day. Nights were hell, because every time I rolled over onto the 'wrong' side, I would wake up in agony.
There's a slight sticky out bit, as I have broken the same rib before. It was really odd, the idea of your body failing for an unknown reason.
Now everything seems to be healing quite fast.
Please don't shout at me, but I did not see my doctor. The last time this happened, no one believed me until someone actually examined me. This took three visits!
Do I have to worry about a 'spontaneous' sort of break (which I understand is common) ?
