I am sorry to hear that, SandyK. Have you talked to the doctor who did your procedure? I'd hope he'd get you back in for a follow-up ultrasound to see if there were any changes in the flow for the worse that could be causing the problems. You might also talk to your neurologist, if there's anything he can do? I've never had hand tremors.
Jdoyen, hope you are doing ok since the second procedure, I can't remember, I know you'd said one vein was blocked but if any other veins were ballooned, maybe there will be benefit from that. All the best.
