Primarily talk to us about it before choosing a treatment for your CTS. Try to find out as much as possible about the injection to which you reacted. These injections contain different steroids, varying or no local anaesthetic and other chemicals such as stabilisers and preservatives. For example, the commercial preparation 'Kenalog' used in this area contains not only the steroid (Triamcinolone acetate), but also sodium chloride, benzyl alcohol, carboxymethylcellulose sodium, polysorbate 80 and either sodium hydroxide or hydrochloric acid used to balance the pH (acidity). You may have had an allergic reaction to one of the other components of the injection or you may have reacted to one of the synthetic steroids which are not native to the human body. It does not necessarily follow that you would also react to a different preparation so knowing exactly which preparation you have had a reaction to is a vital piece of information.
Cortisone injections are extremely safe, but they do still have potential problems. If you are concerned about having a cortisone shot, talk with your doctor. While cortisone is a powerful treatment for many orthopedic conditions, there are usually other options that can also be tried. Many doctors will offer an injection as they are quick, easy, and most often effective. However, your doctor should also be able to offer other treatments for inflammation that may also be effective for those that cannot have, or don't want, a cortisone injection.
