Hello, Welcome to Healthcare Magic. I have read your question fully and understand your concerns. During the thyroid surgery, the skin and the sub-cutaneous structures under the skin are cut to reach to the thyroid gland. During this process a few small nerves supplying to skin structures are also cut. When the ends of the skin and underlying structures are sutured back, the nerves may not be sutured back end to end (as these are very small and can’t be seen). These nerve endings over a span of few weeks to few months will regenerate. During suturing the superficial nerves may also become trapped and hence become irritated. Sometimes during surgery, the nerves could get bruised or inflamed due to pressure from a surgical equipment. These could be the reasons you are having the intermittent needle like pain. This pain will go away with time. You could also try neuropathic pain killers like Pregabalin 150 mg-300 mg twice a day, or Gabapentin 300-600 mg three times a day if you wish. Start at lowest dose and slowly increase the dose based on pain control (75 mg is lowest dose for Pregabalin and 100 mg for Gabpentin). As these medicines are available on prescription, you need to see a doctor. If there is any swelling, redness, the surgical area is warm to touch or any discharge from the incision area, then there could be an underlying inflammation or infection, and it may need treating with antibiotics and anti-inflammatories. I hope this answer has helped you. Thank you Regards Dr Sunita Sayammagaru
