General: Myotoxicity Does not occur, based on current clinical evidence General: Coagulopathy & Haemorrhages Does not occur, based on current clinical evidence General: Renal Damage Does not occur, based on current clinical evidence General: Cardiotoxicity Does not occur, based on current clinical evidence General: Other Does not occur, based on current clinical evidence   First Aid Description: First aid for scorpion stings (in areas where no potentially dangerous species may be found) Details 1. 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. No antivenom is available or indicated. Key Diagnostic Features Local pain, often severe General Approach to Management Most cases will be minor & not require admission.
