These injections can provide relief for several weeks and are recommended for injuries that cause pain and inflammation but do not require surgical treatment. One such condition is frozen shoulder, and cortisone injections can alleviate pain and inflammation in the shoulder joint.
Although cortisone injections offer significant pain relief, they are also associated with certain adverse effects. The most common side effect is a "cortisone flare," where the cortisone crystallizes and causes severe pain for a brief period lasting for a day or two. Applying ice to the injected area can help minimize cortisone flare. Other adverse effects may include skin whitening and infection at the injection site, as well as a transient elevation in blood sugar levels in patients with diabetes.
