My mother, 54, has been diagnosed with osteoarthritis grade 2-3. She gets painless swelling of her feet till knee often. Doctor has put her on Bio D3 max, Ultracet semi, etoricoxio and an arthritis tablet arthryt something. I am not getting convinced with Doctor, but don't have much idea about these tablets. Could you please let me know if these tablet are right for her. What should we do to solve swelling problem?
