Everyone gets aches and pains, and when they don’t go away, we start to suspect that something is wrong. We imagine the possibilities -- osteoarthritis, rheumatoid arthritis, gout, or perhaps we pulled, strains, or bruised a muscle or tendon. Another possibility that may not occur to many is CPPD or calcium pyrophosphate deposition.
CPPD stands for calcium pyrophosphate deposition, but it’s also called pseudogout because the symptoms can mimic those of gout, especially in the knees, ankles, and feet. The condition also goes by chondrocalcinosis and crystal arthritis. CPPD occurs when calcium crystals form deposits in the weight-bearing and other large joints, and in the surrounding tissue. Just using the joints can be painful when the hard mineral deposits push into the space between the bones. Walking, bending, sitting, and standing may be difficult, and more strenuous activities like lifting, climbing, running, or working out become nearly impossible. CPPD is treatable, and there are ways to keep it from getting worse once it has been diagnosed.
