Well,I got bit by one and they are one nasty little you know what! It started out like a little pimple with a red ring around it.Then all the fun began.First,my left hand and wristswelled up,then the pimple grew to a boil.Went to the Dr.and got an RX for an infection(still did'nt think of spider bite)which,did'nt do any good.The "boil" broke open but it was just red raw meat.In a little less than 26 hours,the opening went from the size of a #2 pencil to a little bigger than a silver dollar.Went back to the Dr.,and then right to a hand surgeon.He knew right away what it was and I was in surgery within 45 minutes.So now my left hand is wrapped up like a catchers mitt,but I should be ok in about 10 days,just in time for the pre-rut here in MD...Bob
