Pancreatic cancer

Hi,

I haven't posted on this site for a long time. I had problems with pain on my right side for many months last year and following numerous tests was eventually diagnosed with gallstones. I had my gallbladder removed laparoscopically on 23rd Dec 2019. This procedure went well. However a few weeks before in November I started getting pain on the left side. I went to the doctor numerous times and A&E twice with pain. I had blood tests that came back clear apart from slightly raised gamma glutamyl analyse which was put down to gallstone issue. I had about 3 weeks after the op of no pain but it had now returned intermittently. It radiates to the left flank about where the bra line is. I have no other symptoms but the doctors have said before Christmas it is highly likely to be muscle strain. I returned to the doctor again 2 weeks ago as they were monitoring my BP. I had an ecg which showed an issue they are investigating. But I mentioned the pain again to the doctor but he dismissed it. 
I don't know what to do. I have said so many times about the pain but feel like nothing is being done. When they found the gallstones on the ultrasound they said the pancreas and liver looked fine. Also nothing was mentioned after laparoscopic surgery. Not sure if the surgeon can see the pancreas when performing thus surgery?

sorry for the very long post but getting increasingly paranoid and worried.
