Joint irritation brought on by uric-acid crystal build up in the shared space. An attack is normally excessively painful. The uric-acid crystals are deposited in the combined substance (synovial liquid) and joint liner (synovial liner). Extreme joint infection happens as white-blood cells engulf the uric acid crystals, causing discomfort, temperature, and redness associated with the joint tissues. The word "gout" frequently is used to mention to these painful arthritis attacks but gouty arthritis is just one manifestation of gout.
