Repeated foot joint pain is not necessarily from AIDS and can be caused by many reasons. Repeated joint pain in the feet can be caused by degenerative osteoarthropathy, rheumatoid arthritis, gouty arthritis, systemic lupus erythematosus and other diseases. Therefore, repeated pain in the joints of the feet is not able to determine whether there is AIDS. Clinical judgment of AIDS cannot be based on symptoms. Instead, laboratory tests, such as HIV antibody, HIV antigen or HIV test, must be done to make a clear diagnosis. For joint pain in the feet, it is recommended to go to the hospital as soon as possible for examination and treatment under the guidance of a doctor.
