Does the toradol injection have a lot of side effects? i have severe muscular pain that begins at my shoulder and goes down the side of my back

Depends: Toradol injections either IV or intramuscular can be helpful for pain most likely musculoskeletal abnormalities. It is still a potent anti-inflammatory and needs to be used carefully in patients with kidney, gastrointestinal, or cardiovascular abnormalities. You mentioned specific areas and Toradol should not be injected into a joint for example. Good luck
