Hello and welcome to healthcaremagic
I would keep a possibility of Angioedema. Angioedema or Quincke's edema is the rapid swelling of the dermis,
subcutaneous tissue, mucosa and submucosal tissues. It can be either Acquired OR
Hereditary Angioedema.
I would have liked to gather some more information from you regarding your concern in order to be able to help you better.
-Since how long do you have this problem?
-Are you on some oral medications? Painkillers? Anti-hypertensives?
-Do you also suffer from Hives/Urticaria?
-Does anybody else in your family has the same problem?
Apart from being hereditary, Angioedema can occur due to various other causes like(similar to urticaria):
--Infections(bacterial , viral, fungal)
--Drugs(Pain killers/ antibiotics etc)
--Certain foods and food additives/preservatives.
I would advice you to get few basic lab tests like Hemogram, stool for ova/cyst, Urine routine, Chest X-Ray.
An oral antihistamine like
Fexofenadine (Allegra 180 mg tab) OR
Loratadine (Alaspan 10mg tablet) once or twice daily for a week would be suitable. They are non-sedating and wont affect your alertness level.
If I was your treating doctor I would have also given you a shot of injectable antihistamines like Avil(
pheniramine) and Injectable effcorlin(
hydrocortisone) for rapid relief.
A topical soothing lotion like
calamine would help you symptomatically
take care
