1. going through your occupation [writing/computer work]: It has been proved that prolonged and/or repeated bending-extension movements cause increase in pressure inside the carpal tunnel, and repeated stretching of the nerves and tendons inside the carpal tunnel can lead to inflammation which reduces the size of the tunnel, thus leading to pinching of the median nerve
along with occupation points towards "Carpal Tunnel Syndrome".
3. Articular capsule
of radius (radial flexors of carpal) might have been involved which probably signifies radial tunnel syndrome
[i.e. The dimensions of the groove through which the dorsal tendons of the hand and wrist run are reduced and the pressure resulting from repetitive work activity can lead to inflammation of the tendon]
4. Ask your doctor, physical therapist or an occupational therapist about proper ergonomics and posture to prevent or ease nerve compression.
PS: However, it is necessary to carry out an objective neurological test and EMG/ENG (electromyography/electroneurography) tests.
