<s>[INST] My right side of my brain felt frozen for about 20 minutes. That was yesterday and I had it maybe once or twice before. I used to get migraine headaches on the right side of my head, but after the age of 65 they I stopped getting them. I am now 71 yrs old. Please advise. Thank you [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. There are 2 possibilities to be considered. One is a possible attack of migraine. Second is a possible TIA. The second one is more worrisome and needs scanning of the brain and the blood vessels supplying blood to the brain. I would therefore suggest meeting a neurologist for the same. Alternatively you can visit the ER. As for now, you can try painkillers for migraine. I hope that helps. Let us know the reports and we may be able to help you further. Hope I have answered your query. Let me know if I can assist you further. </s>
