Hand exercises can be beneficial to improve range of movement, prevent stiffness and strengthen the muscles acting around the base of the thumb.
Versus Arthritis have some useful information on osteoarthritis of the hand and wrist, as well as a home exercise programme. This can be found here:

If your symptoms are not improving with self-management, a hand therapist can help you better manage your symptoms through a tailored exercise and management programme. Hand therapists can be accessed via the NHS following a referral from your healthcare practitioner (or privately).

You might find a splint is useful to help relieve the pain you are experiencing in the joint/s. You can find such splints online, or seek help from a hand therapist (an occupational therapist or physiotherapist, who specialises in managing hand conditions) who can mould a plastic splint to fit for you. Do not wear it all the time though, as you may find your joints become stiffer.
