###Human: What is the cure for numbness in head, face and hand with weak convulsions? ###Assistant: Hello. I read carefully your question and would explain that your symptoms could be related to different possible causes like fibromyalgia, vitamin D or vitamin B12 deficiency, tension-type headache related to psychological stress, multiple sclerosis, small vessel disease of the brain, etc. Tanacan can help improve blood circulation in the brain. I would like to know your age and past medical history. I also agree with your doctor on the recommendation for a brain MRI, as it is very important to exclude some of the above possible causes. I would also recommend performing some other blood laboratory tests like complete blood count for anemia, vitamin D and vitamin B12 levels, plasma levels for possible deficiency, PCR for inflammation, thyroid hormone levels for thyroid gland dysfunction. You should discuss with your doctor on the above tests.
