When male genitals are swollen, the first thing to note is whether it is the testicles that are swollen, the skin of the penis that is swollen, or the glans that is red and swollen. If it’s the glans that’s red, it’s probably a case of circumcision and glansitis, and you should pay attention to hygiene in general. If it is the skin tissue of the penis, we should pay attention to whether it is caused by inflammation, or allergy, or because of the foreskin embedded, we need to find the cause to be able to effectively deal with. If it is allergy, should use anti-allergy drugs; if it is inflammation, pay attention to hygiene; if it is the foreskin embedded, must be performed foreskin back; if the testicles, epididymis is swollen, may be epididymitis, should be performed anti-infective treatment, pay attention to bed rest and the use of broad-spectrum antimicrobial agents.
