Gout

Gout is a common and complex form of arthritis that can affect anyone. It's characterized by sudden, severe attacks of pain, swelling, redness and tenderness in one or more joints, most often in the big toe.

An attack of gout can occur suddenly, often waking you up in the middle of the night with the sensation that your big toe is on fire. The affected joint is hot, swollen and so tender that even the weight of the bedsheet on it may seem intolerable.Gout symptoms may come and go, but there are ways to manage symptoms and prevent flares.

Symptoms :

The signs and symptoms of gout almost always occur suddenly, and often at night. They include:

Intense joint pain. Gout usually affects the big toe, but it can occur in any joint. Other commonly affected joints include the ankles, knees, elbows, wrists and fingers. The pain is likely to be most severe within the first four to 12 hours after it begins.
Lingering discomfort. After the most severe pain subsides, some joint discomfort may last from a few days to a few weeks. Later attacks are likely to last longer and affect more joints.
Inflammation and redness. The affected joint or joints become swollen, tender, warm and red.
Limited range of motion. As gout progresses, you may not be able to move your joints normally.
