I'm sorry to hear about the swelling in your neck. Reactive lymphoid hyperplasia, as indicated by your FNAC (Fine Needle Aspiration Cytology) report, generally means that the lymph nodes are reacting to some form of infection or inflammation rather than cancer. This condition is often benign and can resolve once the underlying cause is treated.

Here are some important steps you should consider:

• Follow-up with a specialist: It is important to consult a hematologist or an ear, nose, and throat (ENT) specialist who can evaluate the cause of the lymph node swelling and monitor it over time.
• Further investigations: Your doctor may recommend additional tests such as blood work, imaging studies (like ultrasound or CT scan), or repeat FNAC if the swelling persists or changes.
• Monitor symptoms: Keep track of any new symptoms such as fever, night sweats, weight loss, or increase in size of the swelling, and report these promptly to your doctor.
• Avoid self-medication: Do not start any treatment without professional advice, as the management depends on the underlying cause.

If you experience severe pain, difficulty breathing or swallowing, or rapid enlargement of the swelling, seek emergency medical care immediately.
