Hi
@Sarah69 .
Not for trigger finger, but for damage to bones in hands. One due to arthritic base of thumb, the other was follwing a fall when I broke fingers and scaphoid bone.
Physiotherapists tend to specialise now. E.g. Lower limb, spine, etc.i was very fortunate to be referred to an excellent hand therapy specialist. Good advice on exercises, but I needed to do the work. Also provided correct splints and explained how to use them. Also, advice on different aids and equipment I could use to help manage tasks. A recent fall and more damage means I need their help again, but I have been using the exercises and other info that was useful in the past.
Sorry my conditions were not the same as your trigger finger, but I would definitely recommend you ask for hand specialist physio and or Occupational therapist. Mine helped restore full movements in hands.
I hope someone who has had trigger finger will see your post and give more specific advise from their own experience.
