could a spinal cord overgrowth (swelling on both sides of spine) cause veins to be compressed causing bounding blood pressure? grandfather, mother, 3 siblings (brothers) one has passed already.... all had afib, chr, valve issues, high blood pressure....etc... have had ekg, mri of spine, and only diagnosed with high blood pressure but have bounding a lot and bloody nose since February...... and for that I was diagnosed with sinusitis.
