You’re unlikely to get surgery, unless it’s severe now. The NHS have added it to their list of ‘non-essential’ operations.
I don’t know their criteria. But my wife was unable to sleep for 12 weeks before she had the operation in her first hand. She had no feeling, but pins and needles, and was on a very high dose of gabapentin.
You can go private, but unless you’ve got insurance it’ll be expensive.
Get yourself to the docs, and really try the physio and observe what they tell you to do. If you can a kid it getting bad – you’ll be grateful!
