Hi welcome to health care magic forum. Allergic reaction
will have an itching as well, it appears that you din't have an itching at all.
Face swelling with out itching is suggestive of renal involvement. If it is dental pain it must have severe pain
, so that you have to run to a doctor. it is not there so it is not a dental pain as well.
I consider that you should consult a physician, or nephrologist
for diagnosis and treatment. Besides i advise you to avoid fish, and brinzal to avoid allergy
Wishing for a fast recovery and thanks for calling.
