We live in Fl. & I was walking in grass with flip flop shoes on about 6 hrs ago & I must of gotten stung on the high instep of my foot. It itched & at 1st I thought I d gotten a Thorne in it. I ve taken a benedryl & have put Thera-gesic pain reliving cream on it & it helps temporary. It has a throbbing feel & aching. We couldn t see a bite or mark, but I still feel it aching & throbbing, like a pulse sensation. What should I do & should I be concerned? Thanks Teresa
