Thanks for the query.
By heart finger, I understand you are implying the ring finger (if I am not wrong). Trigger finger is characterised by a catch in the movement of the fingers, when it's bent. It usually occurs as a result of chronic inflammation of the tendon sheaths (commonly in
diabetes and inflammatory arthritis).
Next Steps
If you are suspecting that you are developing any such problem, it is advisable to visit your physician for further advise and treatment.
Health Tips
You may need to start on anti-inflammatory drugs if indeed such a problem is detected.
