This is weird and could be related to my adductor tenderness, or not. I DO have minor hip arthritis, few people my age don’t. No pain…except when I roll over on bed at night after sleeping on that side. At no other time is there pain, tenderness, twinges, nothing. There are no symptoms at any other time whatsoever. Because if this I am not really concerned about it, but am curious if anyone else has experienced this. In order for this to happen, I have to have been resting on that side for quite some time. The pain is right at the side of my hip at the joint, there is no doubt of the location.
