Steroid injection is a good option in experienced hands. There's a minor risk of tendon rupture but we have been doing this procedure for more than 15 years with no complication. In most cases we could avoid surgery.
Hello there we understand your feeling.g and your concern towards your health. Trigger finger is because.of the.inflammation or thickening if fascia in the palm. It would give you lot of pain and won't be relieved even after taking analgesics. Surgery would be the best option for these kind of cases and the procedure won't take much long too. Just consult a orthopedician for your help as early as possible.
Trigger finger is primarily an involvement of the tendon which gets inflammed due to improper ergonomics, trauma or linked to disorders like rheumatoid arthrits etc. It is easily treatable with physiotherapy wherein ultraound therapy/laser therapy has been found to be extremely beneficial.
Also apply ice locally over area of involvement for 4 to 5mins (make sure to remove ice as you get feeling of numbness & reapply it again) twice a day.
Avoid typing function or lifting weights & in severe distress better to use a finger splint while working.
