Has anyone been bitten by a Brown Recluse? I've searched through google for the last couple days and I'm just not sure what bit me. Apparently, where I live, Black Widows and Brown Recluses are the spiders I should be concerned about if bitten. I was in the garage, took my seat belt off and as my left upper arm brushed across the seat side, I felt a sting...and the sensation only became more painful. I instantly itched at my upper arm thinking that maybe something sharp was poking out of my seat, but nothing was there. The pain started to radiate and when I shook my arm, it didn't go away. I noticed a blister like thing, and some redness. It hurt more at that point. I iced it for about an hour and the blister kind of went away, but the red area got bigger. Then the itching started. Bad itching. I did some more research and didn't find any fang marks like a Black Widow may leave. The itching continued and the redness spread. The next day it spread more around the general area where I was bit. The swelling also started. I notice that the skin tissue is slightly hard under the surface. I really have no idea what I was bit by or stung by. I don't have an open wound or bite area that is getting larger or oozing or anything. It is just swollen, a lot of inflamed redness, itchy and painful-with the hardness under the skin. I may be freaking myself out, but I've never had anything like this happen. Something definitely bit/stung me. I never should have googled Brown Recluse bites!! 
Yuck!! I'll try to attach some photos! The red area has increased about three times the size of what the photo shows since taken. Thanks in advance for your advice!
