Last one: Young women may not be able to conceive children as a result of contracting an STD as a teen. This is because STDs like gonorrhea and chlamydia can result in infertility as they can cause PID (pelvic inflammatory disease) in women.
Would it be the upper (ante-) chest (brachial...lung/chest related) area?
I have a better answer
e. You could ask an expert in the hospital
If you don’t change it, it will grow bacteria like mold or algae
