The testicular pain comes and goes and is noticeable in general day to day life (eg now for example). I also have lower abdomen pains which are akin to stomach cramps. I had scans of this area (ultrasound I think) of the area which showed up nothing. GP was then at a bit of a loss as what to do next.
I also have coeliac disease if that is of any relevance.
Can I ask what you mean by lumbar spine abnormality? I do have pain in the right side of my lower back (the same sided as the testicle which is painful). The pain in my back is right by the spine at about waist height if that makes any difference.
On squeeze technique the pain in my testicle is exacerbated by squeezing so I am not sure that would work.
