I think I may have been bitten by a Brown Recluse Spider earlier today. The mark is small, slightly reddish, I feel nauseous, dizzy, itches a little. I live in Illinois (Wheeiing) and did see a small brownish spider on my leg & brushed it off. I have many health issues, type 2 diabetes, high cholesterol, high blood pressure, overweight, bipolar disorder. Should I go to nearest emergency room or wait until tomorrow?
