A case of complex regional pain syndrome occurring after a hymenoptera sting

Abstract A 60-year-old woman visited my clinic due to a hymenoptera sting on her right lower arm 50 minutes previously. She was treated with oral and external applications of corticosteroids as well as oral administration of analgesic and topical cooling. Five days later, she was suspected as having a complex regional pain syndrome (CRPS) with a severe pain of her right lower arm and hand, and erythematous swelling of her fingers of the same site. She was referred to a department of pain management and successfully treated with intravenous administration of Lidocaine, methylcobalamin and neurotropin as well as oral taking of pregabalin and stellate ganglion block.
