This used to show a male diagram but things change with progress I guess. Click on a number associated with the pain area and in the upper left it shows you the spine section that causes pain in that zone.http://www.meddean.luc.edu/lumen/MedEd/GrossAnatomy/learnem/dermat/main_der.htm
It does show that pain can be restricted to just one certain location with nearby areas not affected.
I saved it as a pdf file ages ago if anyone wants to see that version, let me know because I couldn't even get it to upload tonight.
I find that pain in certain areas sets the imagination running more than in others.
For example, I often get pain in my feet, ankles, knees, etc. that I chalk up to fibro and don't give a second thought to.
I'd been dealing with all sorts of bizarre pains for years before finally discussing these with my doctor due to pain that had started happening in my upper chest, which also set my imagination racing.
At the time, I'd never heard of fibromyalgia, or if I had, it hadn't stuck in my mind.
The genital area pain is another one that gets my imagination going.
I imagine I'm not alone in that.
