question: Hi, I have had a numbness in the front/top of my head (trouble remembering what words to use I.e I know there is a word, but cannot remember and have to try hard to remember) blurred vision, a cough with breathing difficulty, tingling in my body/arms. 37 years of age, male.  In the past I had 5 small cysts removed from head, but all were benign.  Thanks
