Are You Sick?

Surgery - Symptoms-Questions

Is this your symptom?

  • Symptoms that occur after surgery 
  • Common symptoms are pain and swelling at the incision site.
  • Other common symptoms are mild dizziness, drowsiness, and nausea (feeling sick to the stomach).
  • Most post-op problems occur within the first 4 weeks after surgery.

Key Points

  • Follow all of your post-op instructions carefully. This will help prevent problems after surgery.
  • It is common for people to have some symptoms after surgery.
  • Mild or moderate pain and swelling at the incision site are common. These symptoms usually peak 2 to 3 days after surgery and then get better.
  • Many people also feel a little dizzy, sleepy, or drowsy. Nausea (feeling sick to stomach), and vomiting (throwing up) are also common. These symptoms usually last less than 24 hours.
  • You can treat mild post-op symptoms with self-care at home.

Problems after Surgery

More common problems that may occur after surgery include:

  • Anesthesia Side Effects: Anesthesia (medicine used to put you asleep during surgery) causes side effects in many people. Common side effects are dizziness, drowsiness, nausea, and vomiting. These symptoms usually get better within 24 hours.
  • Infections: The most common post-op infection is a surgical wound infection. Symptoms are wound pain or swelling that worsen, spreading redness or red streaks, and pus. Other common infections are pneumonia and urinary tract infection. All post-op patients with fever should call or see a doctor right away. Fever can be a sign of a bacterial infection.
  • Constipation: Many factors can cause constipation after surgery. These include anesthesia, pain medicine, poor fluid intake, and decreased activity.
  • Dehydration: Vomiting and not drinking enough fluids can lead to dehydration.
  • DVT (Deep Vein Thrombosis): A DVT is a blood clot that forms in a deep vein. The most common place is the lower leg or thigh. All people are at risk for DVT after surgery. The main symptoms are pain in the calf or thigh and leg swelling.

Other problems include:

  • Bowel blockage: This mainly occurs with abdomen (belly) surgery.
  • Headache after having an epidural for pain
  • Surgical wound hematoma (blood swelling at the wound site)
  • Surgical wound opens up

Prevention

  • Follow your post-op instructions carefully. This will help prevent post-op problems.
  • Keep your wound clean and dry.
  • Follow your activity limits. Avoid any vigorous activity or heavy lifting for at least 4 weeks after surgery.
  • For most surgeries, you can start light exercise (walking on a level surface) the day after surgery. Walking and light exercise lowers the chance of blood clots and constipation.
  • Protect the wound from injury during the month after surgery. At one week after surgery, the tissue strength of the incision is only 10% of normal. At one month after surgery, it is only 50%.
  • Do not smoke for the first month after surgery. Smoking slows wound healing.

Driving After Surgery

Follow the instructions your surgeon gave you. Do not drive if you are taking narcotic pain medicine (such as Vicodin). In general, it is safe to start driving after the following time periods:

  • After any procedure with IV sedation/medicine: 24 hours
  • After general anesthesia: 24 hours
  • After minor surgery (biopsy, vasectomy): 2 days
  • After appendectomy, hernia repair, laparoscopic cholecystectomy: 1 week
  • After laparotomy, hysterectomy, C-section; prostate, bowel or other major surgery: 3 weeks
  • After cardiac bypass surgery, back surgery: 4 weeks

Care Advice

General Care Advice after Surgery

What You Should Know:

  • Follow your post-op instructions carefully. This will help prevent problems after surgery.
  • You can treat mild post-op symptoms at home.
  • Here is some care advice that should help.

Follow Your Surgeon's Instructions:

  • Carefully follow all the instructions your surgeon gave you.
  • If the general care advice below is different, follow your surgeon's instructions instead.

Changing a Dressing:

  • Change the wound dressing if it gets wet or dirty.
  • Follow the dressing directions your surgeon gave you.
  • A dressing that works well is a Telfa dressing covered by gauze. Telfa is a dressing that does not stick to the skin. You can buy it at the drugstore. Place a piece of Telfa on the wound and cover it with a gauze pad.
  • Keep the dressing in place in the same way the surgeon did (such as tape or ace wrap).
  • In most cases, a dressing is no longer needed when the edges of the wound close (usually 48 hours). However, your surgeon may instruct you leave the dressing on longer. This can help protect the wound and catch any drainage.

Keep Incision Clean and Dry:

  • Keep the incision dry for first 24 hours after surgery (use a sponge bath).
  • Your surgeon will tell you when you can remove your dressing. When the dressing is removed, you can shower. Avoid water pressure directly on the incision. Pat the incision area dry with a clean towel.
  • Apply a small amount of petroleum jelly (Vaseline) on the wound daily. You can buy this at the store. This helps protect the wound and limits scarring. Exception: if your doctor recommended an antibiotic ointment, use that instead.
  • Do not bathe or swim for 2 weeks (or whenever the surgeon says it is ok).

Pain Medicine:

  • To help with the pain, take an acetaminophen product (such as Tylenol).
  • Another choice is an ibuprofen product (such as Advil). Ibuprofen works well for this type of pain.
  • Use as needed, but do not take more than the maximum recommended dosage as stated on the package.
  • If you are not sure what to take, ask a pharmacist.

Local Cold for Pain and Swelling:

  • Use cold pack for the first 24 to 48 hours after surgery.
  • Cold helps reduce pain and swelling.
  • Apply the cold pack (or an ice bag wrapped in a towel) to the incision area for 15 minutes.
  • Repeat this once an hour as needed.

Clear Liquids for Nausea and Vomiting:

  • Drink clear fluids in small amounts for 8 hours after surgery.
  • Sip water or sports drinks (like Gatorade or Powerade).
  • You can also drink half-strength, flat lemon-lime soda or ginger ale.
  • Drink small amounts (1 tablespoon) every 5 minutes.
  • After 4 hours without vomiting, you can increase the amount you drink.

Dizziness and Drowsiness:

  • Anesthesia and IV medicines given during surgery can cause dizziness and drowsiness.
  • These symptoms usually get better and go away within 12 to 24 hours after surgery.
  • When getting out of bed, sit up for a few minutes before you stand up.
  • Sit down or lie down if you feel dizzy.
  • Make sure you have someone with you the first 24 hours after surgery.

Do Not Smoke:

  • Do not smoke during the first month after surgery.
  • Smoking slows wound healing.

Activity after Surgery:

  • Follow the activity instructions your surgeon gave you.
  • For most surgeries, you can start light exercise (walking on a level surface) the day after surgery. Walking and light exercise lowers the chance of blood clots and constipation.
  • Avoid any vigorous activity or heavy lifting for 4 weeks after surgery.

What to Expect:

  • Pain and swelling: incision pain and swelling are often worst on day 2 and 3 after surgery. The pain should slowly get better during the next 1 to 2 weeks. Mild itching is common as the incision heals.
  • Redness: mild redness along the incision is common. It should gradually get better and go away. Call your doctor if the red area spreads (gets larger) or red streaks occur. These could be signs of an infection.
  • Drainage: small amounts of clear drainage or a few drops of blood from the incision are common in the first few days. Call your doctor if the drainage increases, becomes cloudy (pus), or smells bad. These could be signs of an infection.
  • Dizziness, drowsiness, and nausea: these symptoms usually get better and go away within 12 to 24 hours after surgery.

Call Your Doctor If:

  • Severe pain
  • Fever
  • Vomiting lasts more than 4 hours
  • Signs of dehydration
  • Wound looks infected (spreading redness, streaks, or drainage)
  • You think you need to be seen
  • Your symptoms get worse
  • Remember! Contact your doctor if you or your child develop any "Contact Your Doctor" symptoms.
