Hi, thanks for writing to HCM.
It is normal to have an exacerbation of pain after a steroid
injection for 1 or 2 days due to crystallisation of the given steroid. For this reason, no vigorous movements or activities are to be done that involves the injected area.
If it is a simple inflammation, the treatment prescribed by your doctor is correct. At times, it is possible that the bursa will get infected and it may be necessary to use an appropriate antibiotic and antiinflammatory medicine for few days.
Hope this information is helpful. Good day
