I've got this vague sensation along or just inside my hip crease on the left side. My PCP says incipient hernia, and that probably is a good diagnosis. I'm 44 and play ice hockey so that would make sense. However I also had literally decades of GI issues that I only recently pinned down to being caused by gluten. No colon cancer in my family, nor in my extended family that I'm aware of.
My sensation is not what I would call pain. It's at worst uncomfortable at times, and I notice it most when I'm sitting or folding over as if to stretch my hamstrings. Driving with the seatbelt going across my lap for a while can start to be uncomfortable. My "rational" brain says it's likely not a tumor in my colon, but I've had a few health problems the last few years which have made me a bit paranoid about what's going on with my body these days. If a colonoscopy was no big deal, I'd probably go ahead and ask for one, but that's not really the case. I know the smart thing to do here is to get a second opinion from a hernia specialist, but thought I'd see if anyone had any thoughts on this.
