Migraines worse with age

Hi all, I’m a lifelong migraine sufferer since the age of 2. Up until the last few years (I’m now 31) my migraines were severe but limited to one every 3-4 months that would last from 1-2 weeks and totally wipe me out. Over the past year, my attacks have become much more frequent at a rate of at least 1 a month that last about a week. Sometimes 2 a month. I’ve been on propranolol as preventative for about 2 years, first at 80mg then at 160mg. Although it seemed to help in the beginning it doesn’t seem to help now. I’m a self employed single mum so as you can imagine, suffering with this is less than ideal. I’m currently waiting for yet another neurologist appointment but I’m wondering if anyone else has experienced an increase in frequency, and if so, had any success in bringing the amount back down? Should mention I have tried most every preventative in the past but nothing ever seems to truly work. I take sumitriptan during attacks which doesn’t seem to work either. Again, have tried most triptans but nothing seems to put a dent in the pain or stop it from running its course. Typically the pain wakes me up at night, goes away with strong painkillers, comes back in a couple of hours. Cycle repeats for days. I have also started suffering with aura which is relatively new to me. I had a couple when I was very young but then no visual disturbances again until I was 27…then again, over the last year have become more frequent. This is particularly worrying to me as I get anxious about driving long distances as they come on so quickly and without warning. Any advice/stories of what has helped will be appreciated. Thanks x
