Complex regional pain syndrome following viper-bite

It is important to be aware of viper-bite as a possible eliciting event for CRPS for early diagnosis and treatment of a patient. As long-lasting pain and oedema are known complications, it is probable that CRPS after viper-bites previously may have been underdiagnosed. As many patients are unaware of being bit, viper bite should be considered in cases of unexplained sudden pain and swelling of a limb.
