As an active ER MD in rural Texas I care for multiple snakebites yearly. The current treatment guidelines recommend no cutting, no sucking, no electroshock, and no tight torniquets. You need to remain as calm as possible and proceed to the nearest ED for assessment. Not all bites envenomate and the degree of envenomation varies from bite to bite. The ER doc will assess your bite and symptoms then administer Crofab if indicated. The most important information is positive identification of the snake if feasible.
