Swelling after inguinal hernia surgery is common: bruising and swelling around the wound, and sometimes of the scrotum and penis in men, are expected after-effects and subside within a few weeks. Pain in the wound for a few days is also normal. However, a wound that becomes hot, red, and more painful, fever, an increasingly swollen or painful abdomen, calf pain, or shortness of breath should prompt a visit to the doctor. Here's what's typical, what concerns the scrotum and testicles, persistent pain, what can help, and warning signs.
Quick answer
After the operation, it is normal to experience pain around the wound for a few days and bruising or swelling around the wound or genitals for a few weeks, according to the UK's National Health Service (NHS). A lump of clear fluid, called a seroma, and bruising extending down the penis and scrotum are among the early complications described by the French Society of Digestive Surgery (SFCD).
The Health Insurance asks you to report to your doctor or surgeon any hematoma that extends to the scrotum, fever, groin pain, a red, swollen, hot or painful operated area, or calf pain.
| Often expected | Note | |
|---|---|---|
| Wound | Pain in the first few days, slight bleeding at the beginning | Red, hot, swollen, more painful, or draining |
| Groin, scrotum, penis | Bruises, swelling that is decreasing | Large, painful hematoma, swelling that is increasing |
| Testicle | Reduced sensitivity for a period of time | Changes in pain, volume, or sensitivity |
| Belly | Bloating after a laparoscopy | Increasingly swollen or painful stomach |

This guide compiles information from the French National Health Insurance (Assurance Maladie), the French Society of Digestive Surgery, and the British National Health Service (NHS) to help you prepare your questions. The written instructions provided by your healthcare team always take precedence.
Emergency: severe difficulty breathing, chest or upper back pain, blood in the sputum, very rapid or irregular heartbeat, or feeling unwell after the operation: immediately call 15 (SAMU) in France, or 112 from any European country. Do not drive yourself.
Is swelling after inguinal hernia surgery normal?
In most cases, yes. After inguinal hernia repair, the NHS lists some bleeding from the wound in the first few days, pain around the wound for a few days, and bruising or swelling around the wound or genitals for a few weeks as normal after-effects. After a laparoscopy, bloating or shoulder pain may occur for a few days due to the gas used to inflate the abdomen.
Swelling or bluish testicles or penis
The dissection is performed near the spermatic cord that descends towards the testicle. A hematoma of the abdominal wall can therefore spread into the penis and scrotum in men, explains the French National Health Insurance (Assurance Maladie), which requests that it be reported. The French Society of Sperm Surgery (SFCD) classifies bruising—those blue patches that spread into the tissues of the penis and scrotum—among the specific early complications of this surgery. These bruises are often alarming; a large, tense, or increasingly painful hematoma should be shown to the surgeon. See Hematoma After Surgery.
A bump at the site of the hernia
A lump may appear where the hernia was located. This is often a seroma, a pocket of clear fluid that forms in the operated area. It generally appears a few days after the procedure and usually disappears spontaneously, explains the French National Health Insurance (Assurance Maladie). The NHS notes that such a lump can last for several weeks or even months. A fluid accumulation that does not disappear on its own is one of the complications to report to your doctor. Hernia recurrence is possible, but rare after the placement of a mesh, according to the French Society of Cardiology (SFCD): only an examination can determine the cause.
Pain after inguinal hernia surgery
Pain around the wound is expected for the first few days. The NHS advises taking the prescribed painkillers, such as paracetamol, and placing your hand over the wound when you cough or sneeze for relief. Follow your discharge prescription rather than general advice. See pain after surgery.
A painful or less sensitive testicle
A temporary loss of sensation in the operated area or testicles is among the side effects that the French National Health Insurance (Assurance Maladie) requires to be reported. The French Society of Cervical Surgery (SFCD) describes a possible impact on sensation above the pubic bone, on the size and sensation of the testicle and scrotum, related to spermatic cord dissection; it can rarely lead to testicular atrophy. A testicle that becomes painful, or changes in size or consistency after the operation should therefore be examined by the surgeon promptly, without waiting for the follow-up appointment.
Numbness under the scar
A numb area under the wound is common: sensation usually returns little by little, but sometimes a small area remains numb, says the NHS.
Pain that lasts
After implant placement, the French National Health Insurance (Assurance Maladie) lists pain that persists for several months as one of the more lasting complications. The NHS also mentions pain or numbness in the groin that lasts for more than several months. This pain is not something to be endured alone: talk to your doctor or surgeon, who can investigate the cause and suggest treatment options.
What helps during recovery
The NHS recommends:
- to take the prescribed painkillers, at regular times if that is the instruction;
- to keep moving, with a gentle activity such as walking, gradually increased;
- to keep the wound covered, clean and dry during the healing process;
- to support the wound with the hand in case of coughing or sneezing;
- to avoid carrying heavy loads and intense efforts until the surgeon authorized them.
The SFCD advises avoiding strenuous physical activity during the consolidation period, the duration of which your surgeon will specify. See the first week at home after an inguinal hernia and the return to work, driving, and sports.
Signs that should prompt a call
Contact the team that operated on you, your attending physician, or the hospital department indicated on your discharge papers as soon as possible if:
- the wound becomes red, hot, swollen or more painful, or pus comes out; the redness may be harder to see on dark skin, the NHS reminds us;
- you have a feverchills, or you feel unwell;
- the wound is bleeding heavily, or a hematoma grows;
- The belly is becoming increasingly swollen or painful;
- nausea or vomiting persist after the operation;
- a calf becomes painful, with a stabbing pain or cramping, which may raise concerns about phlebitis;
- you are unable to urinate.
Chest pain, sudden shortness of breath or blood in the sputum can indicate a pulmonary embolism, warn the National Health Insurance and the NHS: call 15. See fever after an operation , infection of an surgical scar , phlebitis after an operation and difficulty urinating after an operation.
Later: what should prompt a follow-up consultation
After the placement of a reinforcement implant, the French National Health Insurance (Assurance Maladie) lists signs to report even some time after the operation:
- pain that persists over time;
- redness, swelling, pain or local heat that appear some time after the procedure or last for several weeks;
- an accumulation of fluid in the operated area that does not disappear spontaneously;
- pain, fever or persistent discharge at the scar site;
- the reappearance of a hernia in the same place.

F.A.Q
How long does the swelling last?
Bruising and swelling around the wound and genitals usually last a few weeks, according to the NHS; a fluid-filled lump may take longer to disappear. What matters is the progression: swelling that decreases is reassuring, but swelling that increases, hardens, or becomes painful should be examined.
Does a bump mean the hernia has returned?
Not necessarily. Right after the operation, a lump most often corresponds to a seroma or a hematoma. Recurrence is rare after the placement of a mesh, according to the SFCD (French Society of Obstetrics and Gastroenterology). Only the surgeon can differentiate between the two by examining the area: tell them about any lump that persists or reappears. See inguinal hernia surgery.
Is it normal to have testicular pain after the operation?
Discomfort or altered sensitivity may occur afterward, as the dissection is performed near the spermatic cord, explains the SFCD. However, any increased pain, or a testicle that swells, hardens, or changes in size, should be reported to the surgeon promptly.
