The more gout builds up, the more harm it can do

Out-of-control chronic gout can be painful and unpredictable, and cause permanent damage. Even after gout flares end, uric acid crystals from gout stay in your body, settle in your joints, and damage your bones. Uric acid crystals can also build up in vital organs like the kidneys. If you have gout and kidney disease, it’s important to take control of gout because gout can lead to kidney disease progression.

Uric acid crystals could build up so much that visible lumps called tophi form under your skin.
Visible buildup is a sign you may have additional nonvisible buildup in other places.

Uric acid crystals can build up almost anywhere in your body. This means damage can even happen in areas where you never had a flare.
