Hello, Thanks for posting the question in HCM Let me tell you that headache can be due to various reasons like migraine, brain tumor, brain infections, problems in the blood vessel of the brain etc. One strong possibility is that the constellation of symptoms that you have described could be due to migraine.How ever, one has to understand that migraine is a diagnosis of exclusion that means other treatable conditions that result in headache which i have listed above need exclusion before the diagnosis of migraine is made and this is particularly so in a patient who has recent change of character of headache. The fact of the matter is that you also have blurring of vision and pins and needles feelings in face and thumb. Hence i advise you to undergo a detailed neurological assessment by a neurologist. The next step would be to get a MRI scan of the brain mainly to exclude secondary causes that we have discussed above. If your evaluation by neurologist and scans are normal, you donot have to worry much and you will benefit with anti-migraine medicines. Please see a local neiurologist. Hope this will help you Good health
