Yes gout is a form of arthritis, caused by the buildup of uric acid in the blood. When it reaches a certain level it crystallizes in your body and it is like a million little knives when you move. Gravity causes this to mostly keep it in your feet, making it impossible to walk.
In a normal person uric acid is processed and excreted when you pee, but alcohol gets in the way of this, big time. Certain foods are to be avoided, and some non alcoholics that have kidney related illnesses are susceptible to gout, but since I have quit drinking I have not had any issues at all.
