Hey its been like a week since i have discovered a lump under my testicule sack( its like on the canal that you can feel lower from the testicules) its hurting me every time i touch it it feels like it is going to explode . It is like a lump under the skin and it is hard. What is it? P.s im 16 y.o
I'm guessing the canal below your testicle sack that you mention is the root of your penis and the canal is the same tube that is the urethra that carries urine and sperm inside your penis and out the tip? So, it sounds like the lump is in your penis root or skin of it instead of on your testicle?
It might be a small infection in the skin or it might be something else and beginning deeper inside your body. I would go to the Doctor, a local teen or STD clinic, or ask your school nurse to take a look at it. Its not possible to know what it is without a Dr. or nurse seeing it in person and maybe doing some tests to know what it is.
Don't be embarrassed to seek help or talk to your parents about this. All males need medical care at some time. Its no news to anyone that you have normal male body parts that might need some help now and then.
Good luck.
