is a brown recluse or other venomous spider bite? I woke up with these wednesday morning (it's now friday) and the started out more as clear blisters, which then burst and ifi squeezed still exude clear fluid. I ask becuase the last 48 hours or so I have been having pretty bad widespread muscle pain and had a slightly higher temp than I usually run. I am also more fatigued than I can ever remember being. EVERY thing aches me including my neck, back, hips, elbows, knees and feet-even my teeth and jaw are sensitive now. No vomiting or nausea though and the area doesnt really itch, it is just mildly red and a little tender to the touch, but other than that benign. My room isnt as clean as it should be, I dont change my sheets as often as should and I keep the shades pulled 24/7 becuase it is very sunny and will get very hot if shades are open. There seems to be a lot of "creatures" in my house this summer, but my parents say its no different than any other year. My whole house is also a dust magnet and is hard to keep up with it.

I just dont want to go running to the dr though cuz I do have a lot of health issues and frequently have pains and fatigue. i also have a pretty severe form a PMS that goes on for about 11 days, it may be PMDD although I have not been diagnosed. So I just wanted an opinion of whether this looks like it could be a bite. I also know that after a bite, it can take awhile before you get really ill.
