Kenalog has really helped me with OA in my knee, I am only 46 & have needed a knee replacement foe over 15 years. At times I cannot walked because of severe pain in my knee, due to multiple bones spurs. The injections ease the chronic imflammation right away. But the first 24 hours I experience severe anxiety, racing heartbeats, haedaches & unusual hunger. Usually within 3 days my symptons are at almost gone. Along with alot of the pain.
