Reassure the victim. Despite sometimes intense local pain, usually lasting less than one hour, these scorpions are not able to cause major of lethal envenoming and most stings will settle rapidly. 2. Do not apply a bandage or tourniquet, or cut, suck or incise the wound or apply electric shock. Neither the application of local heat or cold are proven as effective. 3. If the victim develops general symptoms or the pain remains severe after one hour, seek medical advice.   Treatment Treatment Summary Stings cause predominantly local effects of short duration, usually not requiring medical treatment.
