any medics - upper abdominal pain... any thoughts?

I suffer from reflux oesophogitis, which has similar manifestations to what you are describing. I think you need to see a GP as there will be many specific questions that they would want to ask before making a diagnosis.

My doctor knows that I will google away if I don't feel fully informed, and said that I should look here for sensible information:

Apparently, it's the same information that GPs access. That said, you should still go to the GP!

Yeah, maybe something like oesophagitis or reflux. Trapped wind?

Is there no way you could to a doctor sooner? Maybe an evening appt?

It wont be pancreatitis, or id very much doubt it. My boyfriend had this 8 times from the age of 18-22. Each time he was very very unwell in hospital. I know you can get chronic pancreatitis, which wouldnt necessarily require a hospital stay but id imagine you'd need to be a heavy drinker or have had many bouts of acute pancreatitis.

Hope u mange to see a doctor soon and feel better.

How weird, I was thinking about this all the way to work. I've had similar 'pains' (although usually it doesn't hurt so much) - for aaaaaages, but at first I thought I'd just been sitting badly or carrying too heavy a bag, because it feels a bit like muscle pain. But recently it's started stabbing on and off, although still not very painful. This morning I was running and I thought I had a stitch, but it didn't go away like a stitch usually did, and it hurt when I started running again. In fact, it still hurt a little bit when I was walking to work.

Dr Google suggests it could be something to do with the gallbladder?
