Do x-rays help to see if I have gout?

Maybe. If your gout is chronic it can effect the bone and create gouty arthritis, if this occurs it will show up on x-ray.
Can be helpful. X-rays are particularly helpful in detecting changes in the bone that are caused by gout. When present these are very specific and can confirm the diagnosis; however, bone changes occur relatively late in the disease. The early soft tissue inflammation of gout is very similiar to other causes of swelling such as infection or injury and is not specific.
