Shoulder bursitis often requires that the fluid in the bursa be aspirated, which involves using a needle and syringe in a sterile environment to remove the fluid. This is typically done at the offices of doctors. Sometimes, the fluid will be sent to an outside laboratory to be analyzed.
If it is determined that the condition is non-infectious, it may be treated with injectable cortisone directly with injections into the bursa that is swollen. This may be done during an aspiration procedure. Physical therapy can help recovery from bursitis, especially if it is also in combination with a frozen shoulder.
