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.
Contact the veterinarian if the pet has abdominal pain, tenderness, or discomfort; bloody, black or tarry stools or blood in vomit; unexplained weight gain; water retention; fatigue or lethargy; skin rash; itching; yellowing of eyes; unusual bruising or bleeding as these symptoms could indicate serious side effects. If any of the following serious side effects occur, stop giving Previcox and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). Other less serious side effects may occur. Continue giving Previcox and talk to your veterinarian if your pet experiences flatulence or diarrhea; dizziness; headache; or insomnia. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.
