Yesterday I had thryoid biopsy with fine needle. It hurts when I swallow and touch it. Like being poked with needlenormal? How long does the pain last?

Thyroid biopsy. Thyroid biopsy may cause pain as you have but that usually does not last long. Give it a day or two and if not improved or worse, contact your primary care physician and he/she will take care of you.
Short time. Hi. Pain from thyroid fine needle aspiration biopsy is minima and short lived (usually no more than a few days). You can take ibuprofen (or any NSAID) for pain. It should pass soon.
