Sorry to inform you of this but a spider probably laid it's eggs inside your leg.I must have shin splints or something. Right shin hurts when I walk, and gets worse throughout the day. It hurt Friday, stayed off my feet as much as I could this weekend. Was fine yesterday and now today it was hurting again. Hurts to drive too. Was just a the grocery store and while walking around I got like a bubbling sensation around my shin. This started about a week ago, and I don't recall anything pieces of wood or anything hitting my leg.
