Hi As you are an software engineer, long hours of typing can leadv to carpal tunnel syndrome because of inappropriate position of wrist during typing. This lead to pain in wrist and fingers. You can video consult with me. I can suggest you proper ergonomic position, also can provide you exercises for same. Thank you.

Your hand -arm-neck muscle are not upto the mark. So you can go for scanning weather any nerve for the same.

Get An X-RAY of Neck & Wrist. It Mainly Happens Due to Cervical Issue or Carpal Tunnel Syndrome. Use Wrist Band . Hit Pack for 15 Minutes Twice Daily . Apply Dynapar Gel For Pain Relief. Neck Shoulder & Wrist Exercises Twice Daily for Three Days.

There are many exercises for strengthening of wrist join and its muscles like  Range of motion, Prayer, Prayer stretch with steeple, Ball squeeze, Rubber band strengthener. I would like to sugeest for an xray of wrist joint to know actual what happened to joint which causing trouble to fingers aa well, may be there is compression of nerve which causes loosing the grip and making fingers pain. Can put your hand in warm water untill wirst and can make mivements of fingers to loosen the tightness. Hand exerciser will be helpfull for betterment of grip and loosening of finger joints.

You can start with the exercises mentioned in this video. https://youtu.be/VubbWFFTlgs If the link is not clickable, just type “wrist pain Nitin” on YouTube and you would get a comprehensive routine to follow for your pain. All the best.
