Good evening... I am writing about a systemic problem I am having with mild to severe join pain. Originally, this began in my left shoulder, and was presumed by the physician to be a pulled / strained muscle. The problem not only persisted, but began spreading, first to the opposing shoulder, then to the left elbow, wrists, left hand, then the lower back, and finally to the hip / groin area and finally to the backs of the knees. It was found I had a highly elevated white blood cell count, coupled with high inflammatory readings, VERY dark urine, and severe joint pain. The condition persisted, not always as bad every day as the last, but in my shoulders, never unnoticeable. I continue to this day with these symptoms. Upon recollection, I remember joking with my wife that a small, 2-dot red mark on that same shoulder (left) was a spider bite, and that maybe that s why the pulled muscle wasn t healing. I then remembered recently I had been under a trailer a week prior to noticing the marks doing plumbing work. After SOME research on spider bites, many of my symptoms resemble a brown recluse bite. My physician seems doubtful, but these are present in our area, and he cannot account for all of these persistant symptoms and is ready to send me @ 50 miles south to a contagious disease testing facility if he has no answers by this Tues. How common are spider bites such as this and do my symptoms fall within the range of being that?
