Hi rose i just came across your story while searching for any CTS answers.
Because your in pain your on medication know is it working?I could have alternative for you but you need to search for that in your own area.

I had pain and i have still sometimes little bit pain but nothing worse,what you need to do is look for for somebody how give percutane electro stimulation or electricity on the needle.
In hospitals they still don't know that this is working and i advice you to look for treatment like this.

Good luck
