My husband has been having these stabbing pains on the right side of his head like behind his eye. This comes very sudden and only lasts a few seconds, but is very painful. This has been goin on for 2 weeks. It also is making the vision in his right eye blurry. He has been to the er and they just give him pain meds that don\'t work. He is a truck driver so he can\'t take to much that makes him sleepy. What could the problem be? Angela.
