Hey all, hope all is well, Several months after developing CFS, I started to feel my heart pumping through my chest. It did not coincide with anxiety or panic or any sort of stressor, and it also is not sporadic. It is a constant feeling of blood pounding through your veins. If I press my hand to certain areas of my body, I can feel the blood pounding through my veins. Shortly after this started, I noticed a definite weakening of the right side of my body. It is not drastic, but it is noticeable and some days it is worse than others. My doctor has put me through 2 ECGs but has found nothing wrong, and also a brain MRI. Does anyone else experience anything similar?
