Fine-Needle Thyroid Biopsy: What to Expect at Home

Skip Navigation

Your Recovery

Location of thyroid gland in neck.

During your biopsy, your doctor placed a thin needle through your skin and into your thyroid gland to take a sample of tissue.

This may have been done to find what is causing a lump or growth in your thyroid.

You may find it uncomfortable to lie still with your head tipped backward. The biopsy site may be sore and tender for 1 to 2 days.

How can you care for yourself at home?

Activity

  • Rest when you feel tired. Getting enough sleep will help you recover.

Diet

  • You can eat your normal diet. If your stomach is upset, try bland, low-fat foods like plain rice, broiled chicken, toast, and yogurt.

Medicines

  • Your doctor will tell you if and when you can restart your medicines. You will also get instructions about taking any new medicines.
  • If you stopped taking aspirin or some other blood thinner, your doctor will tell you when to start taking it again.
  • Be safe with medicines. Read and follow all instructions on the label
    • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
    • If the doctor gave you a prescription medicine for pain, take it as prescribed.
    • Store your prescription pain medicines where no one else can get to them. When you are done using them, dispose of them quickly and safely. Your local pharmacy or hospital may have a drop-off site.
  • If you think your pain medicine is making you sick to your stomach:
    • Take your medicine after meals (unless your doctor has told you not to).
    • Ask your doctor for a different pain medicine.

Incision care

  • Keep the biopsy site covered and dry for 48 hours. A small amount of bleeding from the biopsy site can be expected. Ask your doctor how much drainage to expect.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and contact your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You have severe trouble breathing.

Contact your doctor now or seek immediate medical care if:

  • You have a lot of bleeding through the bandage.
  • You have a hard time swallowing.
  • You have new or worsening pain.
  • You have symptoms of infection, such as:
    • Increased pain, swelling, warmth, or redness.
    • Red streaks leading from the biopsy site.
    • Pus draining from the biopsy site.
    • A fever.

Watch closely for any changes in your health, and be sure to contact your doctor if:

  • You're not getting better as expected.
