Suggest Treatment For Itching And Swelling On Finger Caused By A Bee Sting

Was stung by a bee on my finger 3 days ago. Took 50 mg. Benedryl, after feeling a little itchy. Since the sting, the affected finger is getting more swollen and is very hot. It is deep purple in color with red/purple patches like blood blisters--one of which has split and is weeping. Am continuing benedryl 50 mg. and icing. Is there an Epi-Pen in my future?
