I have some discomfort on my varicocele(left grade 2, right grade 1)when i lift weights above 20 kg.i want to gym but what workouts need to be avoided?

Testicular pain: May be due to the vericocele with more pressure distending the vein with lifting. Blood from left kidney is being forced down the gonadal vein into the scrotum. Answer: Don't lift weight or have an "Internal spermatic vein ligation" to stop the blood flowing down in the opposite direction. Testicle will drain thru other channels.
