I have had a series of both facet block injections and steroid epidurals with my most recent one in August, 2012. I have degenerative disc/spondylolisthesis at L4/5 diagnosed years ago. I am very fit and worked hard most of my life to eat healthy, exercise at an intense level, and keep my weight in normal range. Facet blocks and steroid epidurals will make you gain weight and even though I've continued to exercise and watch my diet throughout my treatments, I have still gained 10-15 lbs.
Some prescriptions like Lyrica will also make you gain wieght very quickly.
Steroid injections can be added to a treatment program that may already include analgesics(pain medications), anti-inflammatory medications, physical therapy, occupational therapy, and/or supportive devices such as canes and braces. Whether one or more of these treatment methods are used depends on the nature of the problem. For example, in an otherwise healthy individual, tendinitis may be adequately treated with only a local steroid injection. However, in a patient with rheumatoid arthritis, injections are generally a small part of a multi-faceted treatment approach.
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.
