My 16 year old son woke up yesterday with what appear to be spider bites. He found a small spider, not a recluse or black widow. The are red, raised, now have a small blisterlike head. Itchy. Today has joint aches, most notably in the ankles and heels, but some wrists, elbows, knees. painful to walk(#8 pain while walking). No fever. He also had two almost healed scratches from a branch that both flared up after the bites. Motrin didn t help. Gave 50mg of Motrin this evening, he takes a daily Zyrtec
