The injection you received today is a combination of local anesthetic and cortisone. The local anesthetic can make you feel better right away but can wear off before the cortisone takes effect which can give you an increase in pain.
To help alleviate discomfort, we recommend that you apply ice several times at the site of the injection for 20 minutes out of each hour.
You can also take Tylenol and Ibuprofen as needed for pain control.
If you are a diabetic, you may notice an increase in blood sugar levels for a day or two following the injection.
If your symptoms persist for beyond five to seven days, please contact your treating physician.
