How are you? What other symptoms are present? Aside from osteoarthritis, finger or joint swelling may be caused by a variety of issues such as gout, other forms of arthritis such as psoriatic or reactive arthritis and even autoimmune conditions like systemic lupus erythematosus. If you can not take the medication prescribed, it is best that you inform your attending physician about this for proper management. Physical therapy for muscle and joint rehabilitation as well as complementary and alternative medicine like acupuncture may also help. Take care and do keep us posted.
