Had it for 2.5 weeks, it's like a stitch (sore, achey, a bit stabby), too high for appendix, too low for liver I think - it's at about 9 o'clock from my navel as you look at me, south of my ribcage. Hurts more when I drive or sit on a hard chair, slightly better when lying down but it's constant and low level, sometimes quite a bit more painful.
Any ideas? Have seen dr who doesn't know what it is...
