I have a borderline high uric acid level for years and every once in a while I get extreme pain in the big toe. This happens only after I happen to squat down on one knee to do some work on the ground and crunch my big toe about 90 degrees. There is no pain at that time, but within a couple of days it turns into a gout attack. Is this a possible trigger or not?
It could definitely be a trigger. The physical stress could cause a rupture of the coating on preexisting urate crystals in the joint so that your immune system senses their presence and reacts in a way that causes the pain and inflammation of gout. Part of the reaction is to recoat the urate crystals so that the immune system no longer detects their presence, thereby limiting the duration of the gout attack.
