Quick answer
What is Paraphimosis?
Paraphimosis is a condition in which the foreskin, once pulled back (retracted) behind the head of the penis, becomes stuck and cannot be returned to its normal position. The trapped foreskin acts like a tight band, which restricts blood and lymph flow, causing the head of the penis and the foreskin to become increasingly swollen and painful.
- How it is treated: Paraphimosis needs prompt medical attention to return the foreskin to its normal position and relieve the swelling.
- Self-care: Prevention centres on always returning the foreskin to its normal forward position after it has been pulled back — for washing, sex, examination, or catheter insertion.
- When to seek help: Seek urgent medical care (A&E) if a retracted foreskin becomes stuck behind the head of the penis and cannot be pulled forward, with swelling and pain — paraphimosis is a medical emergency needing prompt treatment.
What it is
Paraphimosis is a condition in which the foreskin, once pulled back (retracted) behind the head of the penis, becomes stuck and cannot be returned to its normal position. The trapped foreskin acts like a tight band, which restricts blood and lymph flow, causing the head of the penis and the foreskin to become increasingly swollen and painful. If not treated, the swelling worsens and can, in severe or prolonged cases, seriously affect the blood supply, so it is a medical emergency that needs prompt treatment. It is different from phimosis (where a tight foreskin cannot be pulled back in the first place). Paraphimosis often happens when a retracted foreskin is not returned to its normal position — for example after washing, sex, or a medical procedure such as catheter insertion (a common cause in hospital settings), particularly in older men or children. Recognising it and acting quickly is important.
How it is treated
Paraphimosis needs prompt medical attention to return the foreskin to its normal position and relieve the swelling. If it is recognised early, a doctor can often reduce it (push the foreskin back into place) manually, sometimes after reducing the swelling with gentle compression, cooling, or other measures, and with pain relief. If manual reduction is not possible, other techniques or a small procedure may be needed to relieve the constriction, and in some cases a circumcision may be considered later to prevent recurrence. Because delay allows the swelling and any effect on blood supply to worsen, prompt treatment is important. To prevent it, the key message — particularly for carers and healthcare staff — is always to return the foreskin to its normal forward position after it has been retracted (for washing, examination, or after inserting a catheter). The reassuring message is that, treated promptly, paraphimosis is resolved effectively, but it should be treated as an urgent problem.

Beyond medication
Lifestyle and self-care
Prevention centres on always returning the foreskin to its normal forward position after it has been pulled back — for washing, sex, examination, or catheter insertion. This is especially important for carers and healthcare staff. Recognising it early and seeking urgent care are key.
When to get help
When to see a doctor
Seek urgent medical care (A&E) if a retracted foreskin becomes stuck behind the head of the penis and cannot be pulled forward, with swelling and pain — paraphimosis is a medical emergency needing prompt treatment.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Paraphimosis: frequently asked questions
What is the difference between phimosis and paraphimosis?
Phimosis is a tight foreskin that cannot be pulled back over the head of the penis. Paraphimosis is when a retracted foreskin becomes stuck behind the head and cannot be returned forward, causing painful swelling — this is an emergency.
Why is paraphimosis an emergency?
Because the trapped foreskin acts like a tight band, causing increasing swelling and, if not treated, restricting the blood supply. Prompt treatment to return the foreskin to its normal position relieves this, so it needs urgent care.
