For most, a hand roller can be a complementary device to have with a hand massager. It depends on how you use it — applying the wrong kind of pressure can cause discomfort and pain. It is a good way to get started as you can identify spots in your hand that are usually the sore spots and if applying a roller or pressure on the area alleviates or worsens the pain. Consult with a therapist for a more personalized analysis before moving forward.
