I have pimple like swellings on my scrotum, they are not bleeding and not itching at all, i consulted dermatologist he said angiokeratoma on my scrotum then he said they are not harmful(non sexually transmitted) and if i need suggested to go through laser treatment to remove them. I want to know is it curable through laser and if i had laser treatment is it detectable later on in any medical test(Medical fitness for govt jobs ) that i had undergone laser treatment. please let me know doctors.
