Suggest Remedy For Headache, Swelling And Skin Peeling At Insect Bite Site

My wife was bitten by a insect on her finger on Saturday (10/01/2015). She has a bit of swelling, a headache, and the skin on her hands is pealing. What could this be, and what kind of insect could have bitten her? If there is anything else I should know, please let me know. Thank you very much. May god bless you dearly.
