Know if a blister on penis is an STD within 3 days

Are you experiencing a blister on your penis?

Overview of a Blister on the Penis

Let’s get straight to the point: A blister on the penis is not normal. Whether it’s small or large, painful or unnoticeable, red or flesh colored, a penis blister indicates an infection or illness. However, a blister on the penis is usually caused by a sexually transmitted disease.

Possible Causes of a Blister on the Penis

Sexually transmitted diseases are often the main cause of a penis blister. The appearance and nature of a penis blister vary with each STD and each person. The following STDs can cause irregular bumps, blisters, and lesions on the penis:

  • Genital Herpes: A blister on the penis is a common herpes symptom. Herpes causes red, painful, fluid-filled blisters that break open and crust over. Both strains of herpes - HSV-1 and HSV-2 - can cause symptoms in the genital region.
  • Syphilis: Syphilis often causes a single, painless blister, but sometimes more than one penis blister can occur. This blister is usually hard, painless and resembles a bug bite. It will eventually go away on its own, but the STD will still be present in the body.
  • Genital warts: This STD produces warts or blisters on the penis and genital area. Genital warts are usually painless and can appear as a single or multiple warts. These blisters are either flat or raised and can be either pink or flesh-colored.

Penile blisters can be caused by non-sexually transmitted diseases, allergic reactions, or in rare cases, penis cancer.

Diagnosing a Blisters on the Penis

STD testing is a quick and efficient way to diagnose a penis blister. Syphilis and herpes testing can be performed through a quick blood test at a local lab in your area. Results and peace of mind come back in a few short days. Genital warts is usually diagnosed through a visual examination.

Anyone who has ever been sexually active is at risk for STDs. If you have never been sexually active, a doctor can help diagnose symptoms.

Treating a Blister on the Penis

Proper treatment can administered following diagnosis. Herpes is not curable, but treated with antiviral medication. Medication can lessen the severity of herpes symptoms and reduce the frequency of herpes outbreak. Like herpes, genital warts is also not curable. A doctor can freeze off genital warts but the virus will remain present in the body.

Syphilis, on the other hand, can be cured with antibiotics. It's important to treat syphilis promptly, since this STD can cause serious complications when ignored.

Preventing STDs and Penis Blisters

As you may remember from high school health class, the only sure-fire way to prevent is STDs is through abstinence. But let's get real: That's not always realistic or desireable. Routine STD testing - with or without STD symptoms - can diagnose infections, allowing you and your partners to take proper precautions if positive. For example, genital herpes is not curable, but medication can help reduce outbreaks and transmission. Condoms can also help reduce the spread of genital herpes and genital warts.
