Yes, this is suggestive of trigger finger. This condition may occur as a result of frequent use of the fingers as in playing cards, using the keyboard, etc. It may also some times be a part of systemic rheumatic condition. It can spread to other fingers but not very often. The treatment may involve splinting the finger for a few weeks or giving steroid injection over the base of the finger. Sometimes surgery may be needed if all else fails. No medications have been reported useful. In my own experience, 2 tablets of a medicine called phlogenzyme given thrice daily has been successful.
