New account as symptoms are back

Hello
My carpal tunnel has been bad in my left hand and I’ve left it and left it as have been trying to cope with it but it’s freezing up and tingling and loosing sensation during day, driving, hairdressing, and basic day to day things and waking up in night again, even though have hand strap on every night.
Can I have an injection please.
My right hand is much better after having the operation
