This lump can be a lymph
node which has appeared following infection. You need to start on antibiotics and anti-inflammatory drugs after consulting your ENT specialist
. The sooner you start the medications faster the lump will disappear. Regarding your sore throat
and nasal block, drink plenty of warm water, take steam inhalation 2-3 times/day and try using saline nasal drops 3 drops 3-4times/day.
