What Causes Headache, Sore Neck And Blurred Vision?

have a headach and i am tired all the time, Some days my headachs are extreme and the can last for 4 days. My neck is extremely sore to touch and i cant twist my neck very far to the right. When i do turn my neck to the right or look up i get dizzy and blurred vision and can feel clowdy in the head for a couple minutes to a couple of hours.I also on occocasions have pins and needles in my head,arms and hands.I recently had carpel tunnel surgery on both hands but the numbness still comes and goes. Thanks
