I have a pulsation at the front base of my neck. This has been going on for the past 4 years. My heart rhythm has also changed and is more of pounding. Along with this is blood pressure that can rise to 170/100 and drop to 80/60 in minutes. When having an episode a strange sensation of fluid pushing through my head arms and legs and a lot of varicose veins on my left thigh. Lying down, eating, having shower all seem to aggravate the condition. I have visited several cardiologist who say my tests are ok. Could I be having Tricuspid regurgitation? Another cardiologist thinks I might need ablation. Please help me.
