Q: How often do doctors give cortisone injections to a patient? A: We try to limit the injection to one every three months for any single joint, but also we like to limit it to a total of six injections a year for the whole body. We know that the cortisone can sometimes weaken or suppress the immune system and, in diabetics, it raises blood sugar.
The trigger finger came back after 1 year, and I had another shot. Other than the cramps, the finger has been fine for 2 years now. Each cortisone shot gave me 6 months of dizziness, and permanent leg cramps that were getting more severe and frequent. The dizziness want away but not the leg cramps. When I was in my 40s, these injections for sports injuries did not bother me.
