Can a left occipital lesion cause pressure at the top of your head. I have a lesion in my occipita lobe and doctor says its a birth anomoly or low-grade tumor, but only time will tell. But i started getting an increase in floaters in my field of vision w/squiggly lines. I'm getting random shooting pains in my head, down my face, Whats happening to me? Also I've been getting very bad pins and needles all over, strange. What to do.
