Hi doctor recently been experiencing mild pain in my scrotum, my scrotum drops and comes back into shape again, its like they contract. Is this normal? I have been going for a urine test for 3 times now, my results are as fellows; pus cells 2-3, epith cells 4-5. I was told i had a bacterial infection, and this is the third time now, it keeps on reoccurring. What could be the problem, especially the pain my scrotum?
