welcome to HCM! I really appreciate your concern about your sister. I have read the question and from my clinical experience I can say that she has migrainous headaches. As you said migraine is one of the most common problem seen in clinics and is well treatable. It is a feature of migraine that many times the patient had other neurological symptoms as well, along with usual headache, like- visual difficulties, blind spots, flashes of light seen, or numbness, or dizziness, ect. all of these resolve as headache get better or may be after some time in most cases. The point which should be paid attention here is that she is on birth control pill. These pills are hormones, and many times they are one of the causative factors for migraines. You may ask her to start a non hormonal birth control pills or may be go for some other method to pervent pregnancy. I have seen very good results in patients with only this change. talk to her gynaecologist about the same, she can help. Also, she need to check her blood pressure, as all these symptoms-- migraine and numbness and blind spot can be because of it. She should get routine blood test to rule out other causes- lipid profile, thyroid, liver function and kidney function, may be get an eye check up( retina), and ask her to avoid her precipitating factors of migraine ( like: sunlight, remaining hungry, Stress in her case as you mentioned in query or late night working, not getting enough sleep, ect.). I always advice my patients to take the pain killer as soon as she get an attack of migraines, as delaying it and taking drug after 1/2 -1 hour brings only partial relief. In my practice I have seen naproxen sodium with domperidone or tapentadol working great in acute cases of migraine. Hope the reply is useful Please get the tests and start the medicines. Hope she gets well soon! Dr. Manisha Gopal
