I felt a pinprick while collecting and chopping firewood at a ranch in South Texas. Later that night I started feeling body aches, joint pain, and chills.
For this bite actually being the work of a brown recluse: the incident happened within the known habitat of the brown recluse in a wood pile. It's almost clichÃ©.
Against this bite being the work of the dreaded brown recluse: no brown recluse. There was no spider found at the scene of the crime. Of course, that doesn't mean it wasn't a brown recluse bite; it just means there's no way to know for sure.
