Hi,Welcome to Healthcare Magic!The swelling of lips, cheek and neck is called angioedema
.It is most of the time an allergic reaction
to some allergen. It can be due to some pollen, dust, perfume, soap, food, pickle, ornament or almost anything that you are exposed to.It can be a dangerous problem because it can be associated with glottic edema and catastrophic choking
.You should get evaluated by a physician of your locality and get treated and investigations after thorough assessment.I hope the advise would be helpful.
