Please let me know what is the condition of the wrist/hand that is on the opposite side of the carpal tunnel syndrome area?

Dorsal wrist pain: Can be from tendonitis, synovitis ( swelling in the joints), arthritis, tendon avulsion or injury or tear, wrist ligament injury, diseases of carpal bone that affect the blood supply such as keinbocks ( lunate) and preisers ( scaphoid) old fracture, new fracture, non union of fracture, ganglion, benign tumor, malignant tumor, nerve injury, vascular issues and more.

See a Hand surgeon: The commonest conditions on the back of the wrist are the presence of a lump which is usually painless or pain in the wrist secondary to arthritis or degeneration and tenosynovitis. See a hand surgeon.
