You got bit from your poisiness snake what should you do?

That depends on the snake. If we assume it is venomous you need to stop letting that venom into your system now! Tourniquets slow that down. You should try to get the venom out of the system fast. Cutting the area and getting the blood to drip is also good. DO NOT suck out the venom because if you have a cut lip, the venom will enter your bloodstream.

You need medical attention fast. Use the emergency services telephone number of the country you are in. e.g 999 for Britain and Australia or 911 for America
