 Today We'll talk about Urticaria, it's an allergic skin syndrome and can be caused by many different things and that's why it's very common, characteristically has a very sharp border with central color but these symptoms only occur in the skin and the patient has no systemic symptoms whatsoever so the presence of other systemic symptoms like fever, shortness of breath or altered vital signs indicate other causes other than the arctic area the common causes for Urticaria, however, include medications and infections lotions or simply idiopathic.

If we take a skin sample of skin with Urticaria we'll see a widespread activation of mast cells with histamine release acute Urticaria is one that's been present for less than six weeks and more than six weeks is chronic a common presentation for Urticaria especially in exams is a patient who had many lesions all over their body and these lesions would disappear and reappear within hours. Although they normally maintain the same pattern in the same locations this is a key presentation for Urticaria.

Symptoms wise the patient would feel hotness in the area and intense itching it is very important to stop the itch-scratch cycle if the patient scratches the legion would itch more and they would scratch it more and they would itch more and so on the treatment is mainly targeted for chronic Urticaria nursery can use antibiotics like dabs on locally or anti-immunoglobin e like omalizumab which prevents the release of histamine. Other treatments include antihistamines and cortisol.
