Had a sudden swelling in my face neck and jaw and couldn't open my mouth at all. Went to hospital as an emergency and was on IV antibiotics for 3 days. Now I have a hard lump along and above my jawbone on the same side - about the size of an egg.. A dental surgeon is seeing me next week. I am taking antibiotics for a recurrent infection. Do I need any treatment immediately or will it wait? I feel generally unwell.
