Dear All, I earlier had submitted my question that I am having headache from past 12 years which used to occur once a month earlier, then once a week, later every day and now it's constant. I consulted a doctor who told me without any tests that I have anxiety issues and gave me medicines. Initially, it helped me but now the situation got worse and I am constantly having headache. Recently I visited a big hospital about 10 days ago who did my MRI and told me brain has no issues but there is a DNS. He advised me to take medicines for about 6 to 8 months. I want to understand what is DNS. Can that be corrected permanently or would the medication go for a life time. Is there any extra care that I need to take?
