is an advanced stage condition , in which there are various symptoms. It is quite painful , with bowel disturbances.
However , i cannot relate testicular pain
and the string like sensation you mentioned with this disease.It could be due to some other testicular disease
.I suggest you undergo a CT Scan to rule out any other severe disease like IBS, Crohns disease
. Also rule out possibility of gall stones.
Contact me anytime for further advice.
Wish you a speedy recovery.
