I Had A Spider Bite On The Right Side Of

i had a spider bite on the right side of stomach 4 or 5 months ago and i still feel a little pain; originally it was diagnosed as a boil which i had before cleaned it removed the core and no problem my primary doctor now agrees that it may be a bite, what can i do to relieve this pain, mind you the pain isn't acute but on a scale of 1-10 i'd say it is a 3.5 still there.
