I'm 25, normal weight, normal blood readings, don't smoke or drink. I was diagnosed with vestibular migraines (the non-pain kind, mostly just awful dizziness/nausea and weakness) about 2 years ago. Through a lot of trial and error and a barrage of tests, we determined that most of it was caused by hormonal changes and using a lower dose birth control. I switched to a higher estrogen dose, and have been taking 25 mg Amitriptyline for about a year now, and the frequency of the migraine attacks is much better.
The problem is, when I DO have the attacks now, they're different and terrifying! I get shaky, feel freezing, fingers turn blue, feel like my head is disconnected and I'm about to pass out or have a stroke, and my heart pounds. I've found that these usually occur about 4 or 5 hours after having a soda (even half a can!), taking any sort of caffeine (like Excedrin), or getting even the slightest sunburn. I used to drink a lot of soda years ago, with no problems. When the attacks start, I immediately gulp down 2 or 3 full bottles of water or Gatorade, and about a half hour later when I feel like I have to use the bathroom, I suddenly feel better. So I'm guessing the attacks now are caused by dehydration.
The problem is, I drink water constantly, and usually add electrolyte powder. It's all I drink now, for fear of these attacks. I shouldn't be getting so chronically dehydrated, and to such an extreme level! I'm guessing maybe the Amitriptyline is the culprit? Has anyone else experienced this? I told my doctor and we're going to lower my dose to 10 mg. Last night I still had one of the worst of the attacks I've had in a while, and that was 2 weeks into dropping the dose to 20 mg. When I took my BP last night, it was 158/101. Scary.
I'm going to the doctor again today (unfortunately, my old doctor just left. So this one is brand new) for a physical that I had scheduled a while ago. Any suggestions on what to have him look into?
I'm confused and frustrated, because when all this started last year, I did the barrage of blood tests, thyroid tests, and MRI, and all came out normal...I'm not looking forward to doing it all again, especially because often they can't find a working vein, and I end up being poked 20 times. Sigh.
