Gout: It is a type of inflammatory (allergic reaction) to uric acid crystals that form and accumulate inside feet, knuckles, and surrounding bone joints due to high uric acid levels in the blood, resulting in immense pain in joints. The pain may be severe, but the condition improves with medication. To avoid bone and cartilage damage and weakening of the kidneys, repeated gout attacks can require long-term medication. In areas such as the wrists, elbows, feet, or earlobes, chronic gout sufferers can feel small hard lumps forming over time in the soft flesh. These deposits are concentrations of uric acid crystals, called tophi, and over time can cause pain and stiffness. 

Kidney stones: It is a problem in which hard deposits occur in the kidney leading to stones. A kidney stone comprises mainly four types of calcium oxalate, uric acid, struvite and cystine. It is due to the increased level of uric acid in the body. As a result, uric acid crystals start depositing in the kidney, known as renal calculi/nephrolithiasis/urolithiasis.
