Foreskin problems are common in boys and men who are not circumcised. Most are caused by tightness, irritation, inflammation/infection, or scarring, and many settle with the right care and treatment. A small number need urgent medical attention, especially if the foreskin becomes stuck behind the head of the penis (paraphimosis).
This guide covers the most common foreskin problems, what to look for, what usually causes them, and what treatment options are typically considered.
What is the foreskin?
The foreskin is a thin fold of skin that covers the glans (head) of the penis. If someone is circumcised, the foreskin has been surgically removed. If you have a foreskin, it’s important to care for it and pay attention to changes such as new tightness, redness, swelling, inflammation, or lumps.
Quick symptom checklist
Book an assessment if you notice:
- Redness, soreness, itching, rash, or swelling
- Pain or burning when passing urine
- Discharge or unpleasant smell
- Cracking, splitting, or bleeding skin
- Pain during sex/erections
- Foreskin becoming difficult to pull back (new or worsening tightness)
Urgent: go to A&E / urgent care now
- The foreskin is pulled back and cannot be brought forward over the glans (paraphimosis)
- Severe swelling or pain, colour change of the glans, or reduced sensation
The most common foreskin problems
1. Tight foreskin (phimosis)
Phimosis means the foreskin opening is too tight to retract comfortably. In young boys, this can be part of normal development. In teenagers and adults, tightness is more likely to follow inflammation, infection, irritation, or scarring.
Typical symptoms
- Difficulty retracting the foreskin
- Pain or pressure with retraction, washing, erections, or sex
- Recurrent inflammation/infections under the foreskin
Common causes
- Scarring after repeated inflammation or injury (including forceful retraction before it’s ready)
- Infections (bacterial/fungal/viral)
- Skin conditions that scar the foreskin, such as BXO/lichen sclerosus
How it is treated
A clinician may recommend:
- Treating any infection or inflammation first
- A topical steroid (in selected cases) to soften and widen the tight ring, sometimes alongside a gentle, structured stretching approach
- A procedure if symptoms persist, infections recur, or scarring is significant
2. Swelling with a stuck retracted foreskin (paraphimosis — emergency)
Paraphimosis happens when the foreskin is retracted behind the glans and becomes trapped there. Swelling can rapidly worsen and may restrict blood flow. This is painful and needs urgent treatment.
What to do
- Seek urgent care immediately (A&E / urgent treatment centre).
3. Infection and inflammation (balanitis, posthitis, balanoposthitis)
These terms describe inflammation affecting:
- Balanitis: glans (head)
- Posthitis: foreskin
- Balanoposthitis: both
Symptoms
- Redness, soreness, itching, rash
- Swelling and tenderness
- Discharge and/or unpleasant smell
- Sometimes painful urination (particularly if the tip is swollen)
Common causes
- Yeast/fungal infection (a common cause)
- Bacterial infection
- Irritant/contact dermatitis (soaps, shower products, detergents, latex)
- Trapped moisture/urine under the foreskin
- Sometimes sexually transmitted infections (depending on symptoms and risk)
Treatment
Treatment depends on the cause, but may include:
- Gentle washing and careful drying
- Avoiding irritants (fragranced soaps, harsh cleansers, certain detergents)
- Antifungal or antibiotic creams/medicines when indicated
- In some cases, a short course of anti-inflammatory treatment as advised by a clinician
If it keeps coming back
Recurrent balanitis in adults can be associated with diabetes, especially when urine and moisture are trapped under the foreskin. If episodes are frequent, it’s reasonable to ask your GP about diabetes testing.
4. Scarring at the foreskin and glans (BXO / lichen sclerosus)
BXO (balanitis xerotica obliterans), also called lichen sclerosus, is not the same as routine balanitis. It causes scarring and tightening, often at the tip of the foreskin, and can worsen over time.
Clues that suggest scarring
- White, scar-like changes
- A tight fibrous ring at the tip
- Cracking/splitting that keeps returning
- Progressive difficulty retracting
Treatment
A clinician may recommend:
- A course of topical steroid treatment over weeks to months
- Further assessment (and sometimes biopsy) if needed
- A procedure if BXO leads to phimosis/paraphimosis or persistent symptoms
5. Irritation and injury (including dermatitis)
Not all redness or soreness is infection. Foreskin skin can become inflamed due to:
- Friction (tight clothing, repeated rubbing)
- Trapping the skin in a zip
- Irritating products (soaps, bubble baths, antiseptics)
- Allergies (including latex)
If symptoms are mild and clearly linked to an irritant, removing the trigger and using gentler hygiene often helps. If pain, swelling, discharge, bleeding, or urinary symptoms occur, you should be assessed.
6. Dryness and thrush (yeast infection)
Dryness under the foreskin can occur for several reasons, but Healthline highlights Candida (thrush) as a common cause in some cases, particularly when there is redness, irritation, and a change in discharge.
Treatment is typically antifungal medication when a clinician confirms or suspects it.
Foreskin care and prevention
Good care is about gentle cleaning and avoiding irritation:
- Clean regularly with warm water and rinse well
- Avoid strongly fragranced or harsh products
- Dry gently (moisture trapped under the foreskin can encourage irritation/infection)
- Change underwear daily; consider looser, breathable fabrics if you’re prone to irritation
- Use condoms where appropriate to reduce infection risk
For children: never forcibly retract the foreskin. If you’re unsure what is normal for your child’s age, get advice before attempting any retraction.
When is circumcision considered?
Circumcision isn’t the first-line option for every foreskin complaint. It’s usually discussed when problems are recurrent, severe, or driven by scarring, such as:
- Persistent or scarring phimosis
- Recurrent balanitis/balanoposthitis despite appropriate treatment
- Recurrent paraphimosis
- BXO/lichen sclerosus causing tightening or complications
When to seek medical advice
Seek urgent care now
- Foreskin stuck behind the glans and won’t go forward (paraphimosis)
- Severe pain/swelling, colour change, or numbness
Book a routine appointment soon with our urologist
- New or worsening tightness in a teenager/adult
- Recurrent inflammation/infections
- Cracking/bleeding or white scarring changes
- Lumps or persistent skin changes
