What Could Painful Neck And Eyes With Confusion, Blurry Vision And Lack Of Balance Indicate?

Hi Sunday I after exercising I began to have some pain along my neck, forehead and behind my eyes since. I was also suffering from confusion, bouncing into everything inclining people. I have also been having blurred vision. The pain was at a level 10 and then reduced to a 6 by Tuesday. When I was trying to open a car door I was unable to find the door handle and had to have help opening the door. I also had to have constant help while walking in the street. I went to the doctor and was prescribed some Panadiene for the pain. They said that my blood pressure was fine.
