If it is considered to be caused by gout, the uric acid test can be improved. If the cause is separate, for example, the knee joint is considered to be degenerative osteoarthritis, you can have an x-ray examination; if it is considered to be meniscal damage, you can have an MRI examination. If the place of the heel is considered to be bone spur, etc. as well, you can choose x-ray examination. According to the different examination results, then do the corresponding treatment.
