I had colorectal cancer in 2010 and luckily after some radio therapy and surgery, I was lucky enough to be clear.

I've noticed now and then over the last few weeks, I've occasionally had mild stomach pain but didn't think much about it until about a week ago, when a few hours  after eating a meal  I had really bad pain in the middle of my abdomen just below my navel.  It felt like really bad trapped wind and was bad enough to keep me awake some of the night.

This hasn't stopped and although not as severe, I am still getting this pain a couple of hours after eating, which is somewhat helped by emptying my bowels.

Question is, should I get an online Doctors appointment right away or give it a week and see if it goes away?
