Main Symptoms of Balanoposthitis

Balanoposthitis is redness and swelling of both the glans (head) and the foreskin. It can flare quickly and make everyday tasks uncomfortable. The first sign is a patchy or overall redness. The head and inner foreskin look sunburned and feel warmer than the rest of the skin. Itching or burning follows. You catch yourself adjusting underwear or feel a warm sting when urine touches the area. Swelling can puff up the rim. The foreskin may look puffy, and if you’re circumcised, the edge can appear slightly raised. A new discharge shows up. It can be clear, white, or cheesy, and... Learn more

Main Symptoms of Epididymitis

Epididymitis is an infection or irritation of the epididymis—the coiled tube that sits behind each testicle. It usually starts on one side and builds fast, turning a normal day into a careful waddle. The first sign is a deep, throbbing ache at the back of the ball. It feels like someone flicked you hours ago, but the throb keeps growing. Red, shiny skin follows. The scrotum on the sore side turns lobster-colored and feels warmer than the other half. Swelling balloons the sac. The epididymis feels like a thick, tender cord, and the testicle may seem to ride higher or... Learn more

Main Symptoms of Excess Foreskin

Excess foreskin means the skin sleeve covers the head even when the penis is erect, making hygiene and sex trickier than they should be. The first clue is a persistent hood. The head stays hidden unless you manually pull the skin back, and it often slips forward again right away. Smell builds fast. Urine drops and dead cells collect under the fold, giving off a musty odor by midday even after a morning shower. Itching or stinging pops up. The trapped moisture irritates the head, so you catch yourself adjusting underwear or feeling a warm sting when pee touches the... Learn more

Main Symptoms of Prostatitis

Prostatitis is swelling and irritation of the prostate gland. The signs can start suddenly or creep in over weeks, and they often mimic a plain bladder infection—until they don’t. Burning is the first clue. It stings at the start of the stream and can keep stinging even after you stop. Urgency and frequency team up. You race to the bathroom every hour, yet only a small, slow amount comes out. Ache sits deep. It feels like a golf ball parked between the legs, and the pain can shoot into the lower back, testicles, or tip of the penis. Ejaculate hurts... Learn more

Main Symptoms of Orchitis

Orchitis is a painful swelling of one or both testicles, usually triggered by a viral or bacterial infection. It can start suddenly or build over a day or two, turning a normal day into a careful waddle. The first sign is a deep, heavy ache in the ball. It feels like someone kicked you hours ago, but the throb keeps growing. Red, shiny skin follows. The scrotum on the sore side turns lobster-colored and feels warmer than the other half. Swelling balloons the sac. One testicle may double in size and feel tight, as if the skin is stretched over... Learn more
