question: my nephew has just suffered left side paralysis .... the feeling has come back, but he still has pins and needles in his left hand ... he cannot make a fist.... he has a severe headache He is only 28. He has had problems over the last few years which have never been diagnoised... these included high white blood cell count... weight loss ... extreme vomiting without any immediate prior symptoms He has had mri s, cat scans etc and nothing has shown up... do you have any idea what could be causing this?
