someone please answer as soon as possible it happened yesterday
Hi, the condition suggests angioedema which is due to hypersensitivity reaction (type 1).
Drugs like amoxicillin, ACE inhibitors, stress, excitement, cold exposure, prolonged sitting or standing, and ingestion of certain foods can cause such reaction. This is a emergency condition because there will be associated laryngeal edema leading to breathing problems.
It usually involves three types of attack like-
The skin including lips (cutaneous attacks)
The gastrointestinal tract (abdominal attacks) and
The larynx (laryngeal attacks)
The other causes which needs to be ruled out are herpes simplex, infections etc.
Adrenaline, anti-histaminics and corticosteroids are the standard mode of treatment which should be taken after consultation from physician without delay. Take care and regards.
