Is this Brown Recluse? Tampa bay areaAbout week ago felt light headed, headache, had trouble breathing and lots of post nasal drip mucous production choking me at night at same time I also had an ulcerated sore onmy leg that did not start to heal for about a week. I was later told by pest control that the place I moved into had lots of Brown widows around it so I thought I might have been bitten by Brown widow. I showed him the bite scar and he said it was a Brown widow bite. After looking around online I notice that most descriptions of widow bitessay that the bits from widows don't usually cause necrotic lesions. I saw that those types of bites ate usually Brown recluse. I ended up with another sore with pain on my thigh along underwear line. I was hoping it was going to turn out to be a pimple but today I thought I felt a bite on my foot while wearing slippers and a few minutes later I saw a little Spider on the ironing board near me. I took a picture of it and it looks like a Spider with a black violin on its back. Is this causing the necrosis and wounds I am experiencing? Is this a Brown recluse?
