I'm so sorry you're having this exacerbation, you poor thing. Coming to TIMS for support was a very good idea. I'll help you as much as I can.
Positives to remember:
1. Eight months of improvement is EXCELLENT.
2. You are NOT alone.
3. You WILL have recovery.
Having had eight months of improvement is really terrific and bodes very well for your CCSVI future. I've noticed that many pwMS who had the procedure had improvements that lasted for only a couple of months -- you are one of the luckier ones. Please believe that you're not alone -- everyone who reads this post will be pulling for you, some with words of wisdom and some with private prayers, all of which means that the power of positive thinking will be helping you. Keep telling yourself that the worst has passed, and that recovery will come.
did you have an ultrasound to check your IJVs for flow and occlusions? Any sonographer can perform this US; Dr. Zamboni's US protocol used for diagnosing CCSVI does NOT need to be followed when just checking for flow and occlusions.
The ideal first-year schedule for having post-procedure USs is at one month, three months, six months, nine months, and one year. Ask your IR, primary, or neuro to write a script for an "US of internal jugular veins--bilateral," and schedule an appointment at a local US facility ASAP.
An US can detect flow, thrombosis (clotting), and intimal hyperplasia (scar tissue). Make sure your IR receives a copy of the US report, and make an appointment with your IR to review the US and MRI reports (bring your copies of the reports to the appointment).
Don't overly fret about possibly needing a second venoplasty -- some IRs believe it will take two venoplasties to completely finish the job of opening IJVs, especially for valvular stenoses which can tend to have some tissue pop out from the vein wall which can cause thrombosis due to turbulent flow.
Regarding a relapse,
if the US shows good flow, then you might be having an 'MS' relapse rather than CCSVI restenosis. Did you receive steroids which are usually standard protocol for active inflammation? Keep in mind that it can take some time for the inflammation to end and for the lesion to heal.
