Sjogren’s syndrome
This disease mostly affects the glands of the mouth and eyes, and their ability to produce saliva and tears, respectively. It can also affect the skin, and one of the common symptoms for this is itchy and dry skin, just like hives. It can get more serious by developing into vasculitis. The lesions on the skin appear as spots and can take different forms like blister, ulcers, or just lumps. Vasculitis, though rarely, can harm the joints, internal organs, and nerves.
