You need to refer this back to your GP given the amount of meds you're on, mate.
I'm currently in the same boat with my right wrist. The best option is surgery to cut through the ligament through which the nerve routes. I had that done on my left wrist about 30 years ago and haven't felt even a twinge since. It is usually done with a local anesthetic and a benzodiazepine sedative. I elected to do without the sedative so I could watch. It only takes a couple of minutes.
Wait until your age begins with a 7!!
