What causes sharp pain at the cesarean section incision site 20 days postpartum?

Generally speaking, cesarean section refers to a surgical procedure in which a baby is delivered through an incision in the mother's abdomen and uterus. Wound pain 20 days after cesarean section may be caused by muscle tension and recovery of activity, increased sensitivity during nerve regeneration, foreign body reaction to sutures, incision infection, incision hernia, and other factors. If discomfort occurs, seek medical attention promptly. Detailed analysis is as follows:

1. Muscle Tension and Recovery of Activity

During the healing process of muscles and tissues after surgery, newly formed nerve endings may be more sensitive to external stimuli. Combined with the pulling sensation caused by muscle activity at the healing site, sharp pain may easily occur. Adequate rest, avoiding strenuous activity, and performing gentle abdominal muscle relaxation exercises are recommended.

2. Increased Sensitivity During Nerve Regeneration

Nerve regeneration is a process wherein newly formed nerve fibers may temporarily exhibit increased sensitivity when re-establishing connections with the skin surface, leading to exaggerated responses to mild stimuli. Keep the wound dry and clean, avoid friction and pressure, and wear soft, breathable clothing to reduce irritation to the wound.

3. Foreign Body Reaction to Sutures

Some patients may experience an allergic reaction to the sutures or incomplete absorption, resulting in pain around the suture site. Removal of the sutures may be necessary, along with anti-allergy measures to alleviate discomfort.

4. Incision Infection

Incision infection is mainly related to improper postoperative care. Infection can cause local inflammatory reactions, leading to pain, possibly accompanied by symptoms such as bleeding and abdominal pain. It is recommended to follow medical advice for the use of medications such as erythromycin ointment, amoxicillin capsules, and ibuprofen tablets for treatment.

5. Incisional Hernia

An incisional hernia occurs when abdominal organs protrude into the subcutaneous space due to weakness or defects in the abdominal muscles or aponeurosis at the incision site. When intra-abdominal pressure increases, such as during coughing or sneezing, the hernia may enlarge and stimulate surrounding nerves, causing pain, which may be accompanied by symptoms such as nausea and loss of appetite. It is recommended to follow medical advice for the use of medications such as lactulose oral solution, phenytoin sodium tablets, and diazepam tablets for treatment.

Avoid eating spicy, irritating, or greasy foods, which may irritate the wound and cause pain.
