Actually a similar issue happened to someone I know. Do you have the lymph nodes on both sides or just one? What you may have is a fungus growing inside your head, some Dr.'s may call it a "ring warm". If your scalp itches as well that is a side effect.
1. Do hot water fermentation for 10 minutes daily.
2. Take 2 pinches of ginger powder with 1 tsp honey in water daily 2 times for 10 days.
3. Take a homeopathic remedy called Calc flour 30 5pills once bed time for 5 days .
Then wait and watch for 10 days.
