Hi, firstly just see if you can hear any clicking sound while folding it (even if it is with difficulty). Seems to be a trigger finger.
- Activity modifications
- Finger cot splint
- Pain killers if it is more painful (Tab Ultracet once or twice for 7-10 days depending upon the pain)
- Immersion in Luke warm mater and ask her to do folding and unfolding activities regularly
Next Steps
Usually resolvable if she follows the above, as this has started just from past 2weeks.
You can get me back if you want to share any queries.
Take care
