I had trigger finger surgery in February this year - the relief is wonderful. Cortisone shots do not work as well for diabetics so after the 2nd one with no relief (first shot lasted 6 months second shot lasted 6 hours) surgery was my only option. I have a small scar on my palm. The surgery was done as an outpatient, local anthestics and I was home for 3 days (no getting it wet). It still does get achy while handstitching binding but other than that would do it again. Best wishes for a speedy recovery for yours.
