Hi and thanks for the query, Its important that this rash be distinguished from either being of infectious origin or allergic origin. Are others around presenting with same symptoms? Is it the first time you are experiencing this? Any fever or lymph node enlargement? A careful evaluation could really be needed. A food allergy is a possibility but the spread is really unusual. It should be interesting to know the duration of time between consuming alcohol or pee nuts and developing the rash. If it occurred immediately after, it could be incriminated. But if not, other sources should be searched for. Characteristic lesion should easily guide the clinician, depending whether the rashes are vesicles, pustules, macules or papules and other clinical parameters, an appropriate diagnosis could easily be made. Booking an appointment with your family physician or dermatologist could be of interest. Thanks and best regards, Luchuo, MD.
