Thanks for posting your query at DoctorSpring.com. I am Dr.R.K and I am pleased to assist you.
I went through your post about the abdominal in the upper left quadrant radiating to back. The possible causes are peptic ulcer disease, pancreatitis and neuralgia.
Take prilosec and neurontin for relief. If there is no relief, you need to undergo a few tests like upper GI endoscopy and CT scan of the abdomen to find the cause.
I hope that answers your question. I would be glad to assist you further if you have any queries.
