I’ve had hemiplegic migraines since I was 12. I too was hospitalized for 3 days because they thought I was having a stroke. Interestingly enough that was over 50 years ago. My daughter ( 32 years old) also has these occasionally. I now have chronic migraines and migraines with aura but have not had an actual hemiplegic migraine for several years. The best suggestion I have is figure out what triggers yours, make sure you get enough sleep, eat regularly and stay on a consistent schedule. For me my trigger is flashing lights like someone taking my picture with a flash or sunlight glinting on a car window. My daughter is always triggered by strobe lights or police flashing lights. When I was younger there was no medication and I was out of commission for the rest of the day and often needed someone to drive me home. With current medications I can take something and get back to work in an hour or two. I have not let it interfere in anything I do but I ALWAYs carry medication with me! I hope this helps!
