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.
Radiculopathy occurs when something irritates a spinal nerve—say a “slipped disc” causing a pinched nerve. This is also called sciatica . There are resident stem and other cells in the local tissues everywhere in our body. Many live around blood vessels. These are obviously also present in the disc and nerves in the epidural space and they usually play an important role in suppressing inflammation and repairing damage. We know, based on a copious in vitro (lab) data, that the high-dose steroids used in epidural injections can kill these cells. So the progression of the series of epidural steroid injections looks a little something like this:
Lateral and medial epicondylitis are most often the result of repetitive activities such as golf, racquet or throwing sports, or occupation-related movements such as hammering, hand sanding, lifting, or point-and-click motions from moving a computer mouse. Patients typically present with a history of insidious onset of pain and tenderness of the affected elbow region, and a weakened hand grip. The examination reveals point tenderness in the region of the epicondyle, and pain and weakness exacerbated by resisted wrist extension and supination for lateral epicondylitis, and with resisted wrist flexion and pronation for medial epicondylitis.
