Trigger finger

Hey folks... So May last year I developed trigger finger in my ring finger. It happened while at work (arborist) and kinda thought nothing of it, assumed I'd just bashed it. However the triggering went on for quite a while, before I finally saw a good physio who gave me a splint which helped the triggering.

However several months after the triggering stopped I still had a major weaking in that hand and a 'nodule' present at the A1 pulley. I then eventually got a referral processed to get an injection into the pulley. This has helped but im about 10 days post injection, I have some improvements but nothing major... does it normally take some time to get back to 100% or am I more likely to require a surgery? (Which I'm on a waiting list for) Cheers
