Hi and welcome to HCM.Thank you for your querry.
is the last thing to think of in your age. Your pain in testicles may be caused by hernia
. Any infection,genital and systematic can cause inguinal lymph nodes swelling. If pain persists you should do ultrasound
of this lump with needle aspiration. If you are sexually active you should consider STD
ALl in all, in most cases this is nothing serious. Wait few more days and see is there any improvement,if not, do further tests.
WIsh you good health.
