What could cause testicle pain in left testicle only, radiating 20% into lower left abdomen/crevise and 80% in underside left of testicle for 3 months, as follows:
0-1 soreness/pain - when lying down, sleeping, sometimes sitting.
2-3 soreness - when sitting, peeing (muscle soreness only), moving lightly, light bending.
6-8 ache - after nocturnal erections, standing in one spot for 1 hour, vigourous movement with escalated pain lasting about 24-48 hours after the triggering incident, the subsiding somewhat.
I am not sure how this started except perhaps after a week of masturbating more than usual, other than that I had no pain or problems prior to this.Urine
test 3 weeks after aches started was negative.
There is a small cyst like button on lower left underside of testicle, inspected by two doctors who said probably a cyst (it's near tail of epidiymitis)
I have no fever, no major swelling I can see. Was checked for obvious hernias.
