Wrist and knee pain 7 months after taking medication for tuberculosis may be caused by bone tuberculosis, but it may also be caused by other diseases, such as rheumatoid arthritis and gout. Tuberculosis patients generally need to reach the treatment course of 6 to 9 months, or even longer, so after taking medication for 7 months the tuberculosis bacillus is still in an active state, this situation may lead to secondary bone tuberculosis, followed by wrist or knee pain manifestations. However, we can not rule out other diseases that cause wrist and knee pain, such as rheumatoid arthritis patients can be manifested as stiffness and swelling of the joints, pain, impaired mobility, and deformity of the joints. Gout patients can also manifest as redness, swelling, heat, pain in the joints as well as gout stones, etc., especially considering that tuberculosis drugs may cause elevated uric acid and gouty attacks. It is recommended that patients consult a doctor in time, under the guidance of a professional doctor, to clarify whether there is a possibility of secondary bone tuberculosis.
