Ascarillena,
Went through this exact experience myself for about a week or more. Went away and then came back again with a vengience. My vision was so impaired I could not drive (exept to Opthamalogist). Thought I was going to have aneurysm at any time. Had knot on back left side of neck and pain radiated throughout head and behind left eye. Circulation was off and my heart was also affected. Balance/gate was very off.
Took lots of Amla/Enzymes, ran the Cranial Nerve/Brain infection scripts as well as Toxoplasmosis/Trich and OVolv..
Hang in there. You are not alone.
It is with each one of our experiences that brings help and knowledge to someone else on the forum. Could help save a life of another...!!!!!
