I had. Pseudo gout at age 35, and many times in my 70s. It’s usually in my right hand and left knee. I blame it on overuse, it’s caused by crystals that settle in the joints and makes the joint very painful, swollen, and appears just like gout. No one in my family ever had it. I also had my right knee replaced due to sever arthritis and I just assumed my left knee was arthritic too. But, it’s fine, very little arthritis, and the pseudo gout is under control at this time. I’m 83 and suffering with other arthritic conditions right now. It’s an ongoing issue!
