I have had swollen inguinal glands since I was 14. Im now 36. My doctor told me it was due to puberty, but should they still be

My doc told me this when I was 14. I recently had to see a urologist about a lump on my left testicle and when he was examining me he asked about the swollen lymph nodes. I told him what the doctor said and he left it at that. Ive never had any pain or trouble from them, but I would like to know if it is normal to have them swollen for this length of time.

Thanks for your help.
