The corticosteroid works to decrease pain and inflammation. It may take up to one week for you to experience the full effect. The numbing medication will wear off in several hours, at which time you may experience pain or warmth in the injected joint or tissue. If this occurs you may apply ice to the affected area. You may also use a pain reliever such as Tylenol, Ibuprofen or a prescription anti-inflammatory medication as directed by your doctor, unless you have an allergy. It is common to have a slight increase in pain over the next 1-2 days. If you are a diabetic and monitor your sugars, you may also see a temporary increase, which is normal and will resolve. It is also very important that you rest the joint that was injected so the medication has time to work and you don’t cause further inflammation.
