I've had this pain on and off for a couple of years. It started a few weeks after my dad died, and I was feeling very low and ill.
The pain starts under my ribs, like an ache, and then I get stabbing burning pains down my side and round to my back. They start if I feel a cold coming on etc, and I may have a slight temp, and they last for a couple of weeks, before fading away. I may not have another pain for a few months.
In my paranoid state, I have seen the doctor three times (different doctors) all of whom say it is either a type of stomach bug or swollen glands. I had a blood test, which showed a slight infection, but nothing to worry about. No swelling etc.
Anyone else get this?
