As we have seen in another answer, the pain is most associated with the presence of inflammation in the shoulder (tendon and subacromial bursa in particular, long biceps etc …)
In the same way as rehabilitation work, infiltration is a very effective method of reducing inflammation.
Caution: the cortisone used during an infiltration tends to weaken the tendons so is not recommended if a surgical repair of the cap is possible (especially the reproduction of infiltrations).
