Intra-articular glucocorticoid steroid injections can resolve episodes for several months, but there is a risk of later recurrence. Following an injection, the patient normally experiences increased pain over the subsequent day before the steroid starts to settle the condition over the next few days^[1]. As with any steroid injection, there is a small risk of local infection and tendon rupture. Most doctors will restrict giving further courses after two injections, as there is less likelihood of effectiveness but increased risk of side-effects.

As opposed to short-term effect^[2] , the longterm benefits of local steroid injection are less clearly established.^[3]
