I just put on my flip flop sandle to go outside to local apt. laundry and my foot hurt like I had scrated it a little. I looked and saw a bruised and swollen area as big around as a half dollar. I dont have very good site but wonder if this could be a dangerous spider bite. A friend had a brown recluse bite her and she waited to long and they had to take out a large area of tissue in the calf of her leg. I obviously dont have much muscle tissue to spare on the top surface of my foot. WORST PART I am about to travel tomoro and dont have time to go to doctor.! What do you think? My ticket to travel is non refundable!!
