Hand and wrist discomfort at a desk has many causes.
Look at the basics
Posture, desk setup, frequent breaks and gentle stretches matter. Persistent tingling or numbness should be checked by a doctor.
Where the capsule fits
Treat the capsule as an add-on at best. Keep a log of hand comfort and see a doctor if symptoms worsen.
