[|Human|] I have been going to my doctors for several months now because my face swells up on a regular basis at least once a week, this happens at any time of the day or night and last for hours. they have said it could be some sort of allergy but dont have a clue as to what sort, I have been given piriton and an eppe pen. the feeling of this swelling is that I have had ten injections at the dentists and it stays numb for eight hours or more and the swelling is solid it happened at 10pm last night and has still not fully come back to life and this time the swelling was from my mouth right up to my right eye every time this happens it is worse than the last time
[|AI|]  Welcome to Chat Doctor. It definitely appears to be an allergic reaction, a consultation with an immunologist/Allergist for ruling out common allergies by a prick test will help. Maintaining a food diary will help check for any food allergies. Use of a leujotiene inhibitor like montelukast may help. Nonsedating antihistamines like loratadine/Fexofenadine may also be of help. These allergies are usually self limiting and do fade out after some time.
