How often cortisone injections are given varies based on the reason for the injection. This is determined on a case-by-case basis by the health care practitioner. If a single cortisone injection is curative, then further injections are unnecessary. Sometimes, a series of injections might be necessary; for example, cortisone injections for a trigger finger may be given every three weeks, to a maximum of three times in one affected finger. In other instances, such as knee osteoarthritis, a second cortisone injection may be given approximately three months after the first injection, but the injections are not generally continued on a regular basis.
How long does the Cortisone last?
While each patient is different, cortisone injections usually last around 3 weeks. In most cases, however, the shots can last for up to 3 months. While the cortisone shots are surely an option, you must be your own advocate. This includes frequent visits to the podiatrist to monitor any changes in pain management. You must also notify your physician if the pain returns at mild to excruciating levels. Your foot specialist will continue to work in pinpointing the exact causes of your foot discomfort. This can include stress, along with obesity and especially injuries related to sports or even walking. The ultimate goal in using cortisone shots is to reduce the pain, swelling, and inflammation associated with PF. If after 3 weeks you still see no significant change, your podiatrist will evaluate the situation and recommend further steps to be taken (. orthotic therapy and/or taping )
