Hi Darwin, I've had this sort of pain for nearly 3 months - had an endoscopy, nothing showed up, now am awaiting an ultrasound. My pain is left upper, under ribs, sometimes in the armpit, around the side into my back and lower back and then sometimes round to the groin. My stomach is tender and if I push on it I can feel something move from one side of the abdomen to the other. I've lost about a stone, yet my waist has increased by an inch - all this started on 29th July and the pain has been constant from that day to this. Pain is not terrible but still wakes me up every hour or so at night. GP was initially very dismissive, consultant was even worse! If you google pain in left side etc you get loads of forums discussing just that, people who have had this for years without answers. So does that mean we should say phew, its nothing to worry about, or make a fuss on the grounds that it could be a cancerous tumour waiting to grow?! Anyway do let us know if you have any more news, good luck,
