Monday night my dog was rough housing and had a cow femur bone in her mouth, while i was petting my male puppy, she came over and hit me over the left side of my head with the bone. It really hurt. Tuesday felt fine, however today I felt the odd dizzy spell when moving fast, and woke up with a horrible neck pain in the left side and a constant headache. I am also 18 weeks pregnant. What should I do?
