Hi,  I feel a round fat like structure in there inside my cheek which is not visible and is present just near the joint of my jaw, below my ear.  If I pinch my cheek then I can feel that lump of fat or gland (which I am  not sure) is slipping from the pinch.  I have pain in the jaw and feeling of soreness in the mouth and unable to eat.  Is this related to any dental problem ??  Please suggest.
Just ahead of the joint of jaw is a gland called parotid gland. Sometimes, usually in cases of deny Chat Doctor.  Please take a course of broad spectrum antibiotic like amoxicillin+ clavulanic acid and metronidazole for 5-7 days along with a painkiller. Also maintain, oral hygiene and use mouth wash after every food intake. Increase the water and fluid intake so that there may be no dehydration. Hope it will help you. If, pain increases and becomes throbbing and unbearable, please show it to a surgeon for management of the swelling.
