Common side effects after pacemaker surgery include swelling, tenderness and pain near the incision site, according to MedicineNet. Although serious complications are rare, they include blood vessel damage, nerve damage, collapsed lung and infection.
To lessen pain and swelling after surgery, doctors often prescribe over-the-counter pain medications, such as ibuprofen or acetaminophen, according to Mayo Clinic. Antibiotics may also be given during or after surgery to reduce the risk of infection, explains MedicineNet.
In most cases, patients spend one night in the hospital after surgery for monitoring, reports MedicineNet. It is normal for mild pain and swelling to persist for a few weeks after surgery, and the doctor may recommend avoiding strenuous activities or heavy lifting until healing is complete.
