Sorry to hear you are suffering. I’m very similar to you in that I have 24/7 symptoms which have been ongoing for almost 16 months. Whilst that sounds bad, I have made some progress since being really poorly in the Autumn of 2018. I have been doing a lot to monitor my triggers and from that, I can tell my really bad flare ups appear to be from fluctuating hormones, barometic pressure, allergies, stress and - to a lesser extent - diet.
I have installed the Migraine Buddy app on my phone and that is a really useful way of recording attacks and getting an idea of what might be causing them. In a typical month, I seem to have a pattern of between 7-10 days of baseline 24/7 symptoms where I can function at around 80%. For the remainder of the month, my symptoms really ramp up and I’m then in a pattern of symptoms lasting on average for 19 hours. I get a short break and then another comes along for about the same time. When this happens, I feel I only really function at about 50% due to the head pressure, awful bouncing floor feeling and mini vertigo spins (made worse by visual stimuli). For me, the only real relief I get is when I’m travelling in a car, bus, train, etc. Being in motion seems to help.
Med wise, I’m quite sensitive so I’m cautiously on 10mg Amitriptyline which I take daily at night. I believe it gives me some relief and a better night’s sleep for sure. If I happen to get pain with my migraine (and that’s rare) then I take paracetamol and that definitely helps and occasionally lessens the spinning sensation. I was trialling acupuncture before the Covid-19 pandemic took off and I believe that was lessening the head pressure as well as the terrible anxiety I’ve developed from having this condition. I’ve found that reducing the head pressure reduces the vertigo sensations. I’m hoping to resume acupuncture once it’s safe to do so.
I hope this helps you in some way and that you find some relief for your symptoms soon. This is a great site and has some wonderful tips to help you cope. It has been a lifesaver for me.
