It is well known that cortisone is a powerful anti-inflammatory agent but it also has a mild softening effect which can be very useful when the condition has a narrowing or tightening component. I inject a mixture of hydrocortisone and a local anaesthetic, usually lignocaine or sometimes bupivicaine.
Generally the response falls into three broad groups. In some people the response is very quick within a few days, but in the majority of patients it may take 2-3 weeks for the injection to work. If it hasn't worked by 6 weeks then it is unlikely to work.
