Negative to that. If I put my right hand over my right side and my left hand over my left side, it feels identical, which is the feel of a muscular contraction.
I would add this. This is an area which has bothered me to a much lesser extent before. And my doctor had not detected any indication of hernia when I mentioned it. That was in August. This is much more intense. It could be a scarring reaction from the suregery a couple of years ago. It might have expanded and pressured a nerve. Just a thought.
