Thyroid Fine Needle Aspiration

You have had a procedure involving the insertion of a small needle into your thyroid gland. The needle took out a small amount of tissue that will be examined by a doctor that specializes in looking at tissues. Your doctor will notify you of the results of your biopsy. Since this procedure required the insertion of a needle, there is slight risk of bleeding, tenderness and rarely an infection.


  • You may return to work today.
  • Avoid any vigorous physical activity for 24 hours.

Symptom Control

  • If you have pain and tenderness at the site, you may take your usual or recommended pain medication.
  • Do not take any aspirin the day of the biopsy.
  • You may feel more comfortable lying with your head partially raised.
  • Avoid strain on your neck by putting both hands behind your neck to support your head.
  • You may develop a sore throat.

Biopsy Site Care

  • You may have a small amount of bleeding at the site.
  • If this happens, you should lie down and apply gentle direct pressure to the bleeding for 10 minutes.
  • When the bleeding has stopped, apply a new band-aide.
  • You may develop bruises where the needle was inserted.
  • Bruising is normal.
  • The bruises should fade in a week to 10 days.
  • Keep the band-aide on for 24 hours, then you may remove the band-aide and shower.
  • You may put on a clean band-aide or leave the site uncovered.

When to Call Your Provider

  • If you have a fever over 100 degrees.
  • Increased redness or swelling at the site.
  • Persistent drainage or pain around the site.
  • If you experience persistent bleeding, difficulty breathing, neck swelling or difficulty swallowing, please have someone take you to the nearest emergency facility.

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
President and CEO
