I have this symptom. It drives me crazy. The only thing that helped it was heparin for hypercoagulation. It was gone during the 10.5 months I was doing the heparin shots but it came back about 2 months after I stopped them. Let me know if you find out what this is from! Hope you finds something that helps you as the swooshing is very annoying.
