What Causes Sharp Pain In Leg Radiating To Back And Head Along With Dizziness?

Hello my name is Cyndi. My problem is that I have bad pain that first started in my leg. Started having sharp pain in my leg and foot. It would also go numb. Now it s up my back to my spine and now in my head. I m having sharp pain in my head also. I m very dizzy all the time and my eyes burn and water all the time. I wake up dizzy and can t hardly see. Please help. I ve told my doctor but without doing a MRI or ct scan just automatically diagnosed me with fibromyalgia. I don t think it is. My legs are very weak and my arms. I have numbness and tingling in my feet and arms also. What is going on? I m worried.
