Injections- General

 

  • The purpose of the injection is to eliminate the pain or numbness/tingling caused by your condition.
  • The injection is a combination of a local anesthetic and a cortisone preparation.  The cortisone solution decreases the inflammation in the involved area. The local anesthetic will cause temporary numbness or decrease in the pain.
  • The area to be injected will be washed with an antiseptic cleanser.  A small needle will be used to inject the preparation. You will probably feel fullness at the injection site.
  • After the anesthetic wears off you may experience some pain for a few hours. A small red spot may be noted where the needle went through your skin.
  • The risks of an injection include but are not limited to: infection, tendon and nerve injury.
  •  It is also possible to get fat atrophy and depigmentation at the site of the injection.
  • The cortisone may upset your diabetic protocol and if that is a problem you should contact the physician who takes care of your diabetes.
  • You may get the injection site wet and shower normally.
  • Pain can be managed with ice and/or Tylenol or an anti-inflammatory if you normally can use them. Ice may be applied with an ice pack.  A towel should be placed between your skin and the ice. You may also use an ice cube to rub over the sore area.  Do not leave the ice cube in one spot on your hand for any length of time.
  • Wearing a splint as much as possible for the next 24 hours may be helpful for after some injections.
  • The pain caused by the condition will return after the anesthetic wears off and before the cortisone works. Therefore be prepared and use the medications and precaution you used before the injection.
  • The injection will start to work in approximately 2 to 5 days. Full benefit will be noted in 3 weeks
  • Fever, severe pain, or redness could be signs of an infection.  If these are noted, you should call your doctor immediately.
