Frequency, severity and duration of flare-up in symptoms in patients with joint and tendon-associated inflammation after treatment with ultrasound guided steroid injection-a prospective cohort study.

The severity and duration of flair-up symptoms (temporarily increase in symptoms after treatment) after local steroid injection therapy are unknown. Whether the region treated, severity of inflammation or distribution of medicine plays a role are unclear. The aim of this study is to register flair-up symptoms after steroid injection and relate any symptoms to region, present of inflammation and distribution of medicine seen on ultrasound examination. The results of this study will enable more sufficient information on flair-up symptoms to patients treated with steroid injection therapy
