Hello, I was diagnosed with ITP at 11 years old. Long story short it practically went away I just check my platlet count regularly to be sure. Since then I've had other health problems and I've always wanted to see if they could be related. I have a high amount of PVC which make my heart rate really high even when I'm relaxing. It makes me feel lightheaded dizzy and like I'm running a race all while sitting. I've also always have a headache. They are located most often on the front of my head and the pressure is located behind my eyes. I also get very bad migraines. Some days my vision gets very blurry and I can't even eat anything. I've tried a few medications for migraines but they always negatively effect my heart. And nothing was abnormal on my MRI. This is the first time I've stumbled upon this website so I thought I would ask and see what happens.
