Vasculitishttps://en.wikipedia.org/wiki/Vasculitis
Vasculitis is a group of disorders that destroy blood vessels by inflammation. Vasculitis can be classified by the cause, the location, the type of vessel or the size of vessel. Laboratory tests and skin biopsy may be required to find underlying causes. Treatments are generally directed toward stopping the inflammation and suppressing the immune system. Typically, corticosteroids such as prednisone are used.

Diagnosis
Vasculitis limited to the skin may improve over time. However, blood and urine tests may be done to detect systemic or autoimmune disorders.

Treatment ― OTC Drugs
If vasculitis is limited to the skin without invasion of other organs, a steroid ointment could be used.
