For the past 7 months i have had lack of sensation in my right forehead above my eyebrow. I have had a brain CT (normal), lumbar and cervical spine MRI (normal), countless blood tests for b12, thyroid etc (all normal). And have seen 2 neurologists with no answers as to what is causing this. It is not completely numb but just enough to make me skin feel tight in that area and a little difficult to lift my right eyebrow. When this all first started the numbness was spread over my entire right side of my face with scalp, temple, forehead and right of nose all numb. Along with a constant headache. However that seems to have ceased and now I am left with just this nagging numbness on my forehead with no explanation. Any advice is reassuring.
