What Is Genital Dysesthesia? Understanding the Condition

Genital dysesthesia is part of a group of neurological conditions called cutaneous dysesthesia. These conditions cause persistent pain or itchiness without any apparent skin damage. 

Dysesthesia around the genitals in men is also called burning scrotum syndrome, scrotodynia, or red scrotum syndrome.

The cause of genial dysesthesia is often unclear, and for some people, it can significantly affect quality of life. The condition is rare, so it’s been challenging to determine the optimal treatment plan. Some people find relief with medications or other remedies.

The hallmark symptom of genital dysesthesia is the presence of uncomfortable burning sensations around the genitalia. This burning is often described as a persistent feeling of internal heat, even when there's no visible redness (erythema) or irritation of the genital skin.

Other signs and symptoms can include:

• Itchiness (pruritus) around the penis or scrotum

• Scrotal or penile tingling or pins and needles

• Numb penis

• Pain if the genitals rub against clothing

• A feeling of constant pressure around the genitals

• Irritation even with light touch to the penis or scrotum

These sensations can be constant or come and go in response to triggers like stress, certain activities, or even changes in weather.

The underlying cause of genital dysesthesia is often unclear, but it’s typically assumed to be related to nerve dysfunction or irritation.

Causes of genital dysesthesia in men may include:

• Nerve entrapment or compression. Nerve entrapment is when something pushes against your nerve, such as bone, swelling, or soft tissue. This may lead to overactivity of the nerve that causes excessive firing and the sensation of pain.

• Neuropathies. Neuropathy is a catchall term for nerve damage. One common cause is diabetic neuropathy, which is nerve damage caused by chronically high blood sugar levels. 

• Trauma or injury. Direct trauma to the area around your genitals may cause nerve damage. Damage to the pudendal nerve in particular is known to change sensation to the genitals. 

• Infections. Some infections like herpes zoster (shingles), can leave lingering nerve damage, called post-herpetic neuralgia.

• Spinal cord issues. Nerves to your genitals originate from your spinal cord in your lower back. Compressed nerve roots there can cause a condition called radiculopathy, which can trigger abnormal genital sensations.  

• Central sensitization. Sometimes, the nervous system becomes "wound up" and hypersensitive, often after prolonged pain or stress. This means that even minor stimuli can be perceived as intensely uncomfortable. This is a complex phenomenon in which the brain and spinal cord malfunction while processing pain and other sensations.

• Medication side effects: Certain medications can have neurological side effects that manifest as dysesthesia. Overuse of high-potency topical corticosteroids has been linked to genital dysesthesia. 

While anyone can develop genital dysesthesia, certain factors increase the likelihood. 

• Age. When it occurs in males, genital dysesthesia seems to be most common over the age of 50.

• Skin tone. Genital dysesthesia is thought to be most common in people withvery fair skin tones.

• Diabetes. Poorly managed blood sugar increases the risk of diabetic neuropathy, which can affect any peripheral nerve, including those in the genitals.

• History of pelvic surgery. Procedures like prostate surgery carry a risk of incidental nerve damage or entrapment during the healing process.

• Prolonged cycling or sitting. Activities that put sustained pressure on the perineum, like cycling, may compress nerves, particularly the pudendal nerve that provides sensations to your genitals.

Diagnosing genital dysesthesia is primarily a process of elimination. Your healthcare provider will likely order a series of tests to rule out other conditions. 

They will likely also:

• Perform a physical exam to inspect your genitals for any abnormalities

• Ask about your symptoms

• Consider your personal and family medical history

If further testing is needed, you may be referred to a specialist in dermatology or neurology. Additional tests you might receive include:

• Skin swabs

• Urine tests

• STI tests

• Patch skin tests to rule out allergic contact dermatitis in the affected area

• Skin biopsy

• Imaging (such as an X-ray, MRI, or CT scan) of your back, spinal cord, or pelvis

Male genital dysesthesia is rare; little is known about how to best treat it. Most of the current treatment options come from case reports where researchers look at the effect of treatment on a small number of people and observe the effect. 

Some of the current options include the following.

Medications

Some medications that are used to treat genital dysesthesia include: 

• Neuropathic pain medications. These are often the first-line treatment. Gabapentin (Neurontin) and pregabalin (Lyrica) are common choices, working by calming overactive nerve signals.

• Tricyclic antidepressants. Low doses of drugs like amitriptyline or nortriptyline may be prescribed for their nerve-calming properties.

• Ivermectin. Ivermectin is primarily an antiparasitic drug, but it is under investigation for treating dysesthesia. 

• Doxycycline. Some research has found improvements in symptoms with the antibiotic doxycycline, possibly due to its anti-inflammatory properties.

• Muscle relaxants. If pelvic floor muscle spasm is contributing to nerve compression, muscle relaxants can be helpful.

• Topical treatments. Lidocaine patches or creams can provide temporary local numbing, and topical steroids may help reduce inflammation if it’s present.

Other Treatments

Some lifestyle changes or in-office procedures may also provide some relief, including:

• Physical therapy. Physical therapy may be recommended, especially if your healthcare provider suspects you have nerve entrapment or muscle tension. 

• Nerve blocks. Nerve blocks involve the injection of a local anesthetic around a nerve to prevent pain. They may provide temporary relief, and, if they do, that helps confirm the source of the problem.

• Botox injections. One case study found that injecting botulinum toxin into overly tight pelvic floor muscles helped relax them, reducing nerve compression. More research is needed to fully understand the effects of this approach. 

• Psychological support. Living with chronic, unexplained sensations in your genital area can take a significant toll on your mental health. Therapy, particularly cognitive behavioral therapy, can help you reframe thoughts about the sensations and learn coping strategies.

• Experimental treatments. For severe cases that don’t respond to other treatments, your doctor may consider treatments like spinal cord stimulation or peripheral nerve stimulation. These treatments involve stimulating your nerves with an electrode to try to modify pain sensations. 

The cause of genital dysesthesia often isn’t identifiable, and it may not always be possible to prevent it. 

Some potential ways you may be able to prevent your chances of developing nerve-related pelvic conditions include:

• Managing diabetes. If you have diabetes, follow your treatment plan to help prevent diabetic neuropathy. 

• Modifying activities. Cyclists may want to invest in a well-fitting, pressure-relieving seat and padded shorts to take pressure off nerves in the genital area. 

• Following post-surgical care instructions. If you have pelvic surgery, it’s important to follow your post-operative instructions to avoid complications. 

• Treating infections promptly. While dysesthesia isn't an infection, effectively treating conditions like shingles or other viral infections can reduce the risk of neurological issues. 

• Listening to your body. Anytime you experience new or unusual sensations, especially after an injury or change in activity, talk to a healthcare professional. Consulting with them early may help you prevent minor issues from becoming larger, long-term concerns. 

And if you’ve previously been diagnosed with genital dysesthesia, it’s important to go to all your follow-up appointments with your healthcare provider.

Genital dysesthesia is a poorly understood condition that can affect your overall quality of life. It’s characterized by abnormal pain or sensations around your genitals, even in the absence of noticeable changes to your skin. 

Researchers are still investigating the causes of and best treatments for genital dysesthesia. Your doctor may recommend medications to help reduce nerve pain.

Is genital dysesthesia a psychological condition?

While psychological factors like stress and anxiety may play a role in dysesthesia for some people, it’s generally thought to originate from abnormal nerve signaling.

Can genital dysesthesia be cured?

There is no known permanent cure for this sensation yet, but symptoms can be managed. Some people with genital dysesthesia may have symptoms for a short while and never feel them again. Others may have recurring flare-ups. 

How long does genital dysesthesia last?

The duration of genital dysesthesia varies widely. For some, it might be a temporary issue that resolves with targeted treatment. For others, it can be a chronic condition requiring ongoing management. 

Will genital dysesthesia affect my sex life?

Genital dysesthesia might affect sexual function and intimacy if physical contact is painful. Talk to your healthcare provider about ways to reduce this pain. 

What kind of doctor should I see for genital dysesthesia?

Your first visit may be with your primary care doctor. They may refer you to a neurologist, who has more specialized knowledge of the nerves.
