Hello & welcome,
As you have undergone extensive procedure of wisdom teeth removal , swelling and infection are the conditions commonly associated with it after the procedure.
If there is lump present, that clearly indicates the presence of associated infection & sometimes it might become quiet painful.
Visit your
dentist who removed your wisdom teeth, get clinical examination thoroughly done to diagnose any remaining suture material in the wound or presence of any type of secondary infection.
Antibiotics & Anti-inflammatory drugs are very vital in such condition to arrest the infection from spreading in surrounding tissue.
Even, if your dentist finds that the infection is severe, then Antibiotics might be needed to be administered by intra-venous rout for faster results.
Don't take these drugs without consulting your dentist as random use of the drugs may worsen the situation.
Keep your oral cavity clean as much as possible with proper use of brushing done regularly & with antiseptic mouthwash.
Avoid hot fomentation or eating hot food or drinking hot drinks like tea & coffee as heat may aggravate the swelling.
Take care.
