Hello,
I see that you are having the problem of chronic urticaria.It is defined as
urticaria that persists for longer than 6 weeks.
In most of the cases of chronic urticaria, the underlying pathology is idiopathic i.e it is not linked to any cause. It is essential to rule out the presence of serious illnesses of which recurring hives can be a symptom. Examples are hepatitis, hyperthyroidism, lymphomas, collagen vascular diseases, and cancers of the rectum, kidneys and gastrointestinal tract.
