Good catch SassyLassie! It didn't occur to me the pain was from the injection in the butt. Tenderness is often the result of injecting very viscous medications, but after a week the pain should have subsided. Talk to your doctor.
Hi
Do you mean you have pain in the injection site? If so, the health care provider could have hit a nerve. If this is not what you mean, I agree with Care Giver, some tests should be run to find out what is causing the pain.
You don't provide much of a history.
"Butt" pains are usually due to sciaticia and a proper diagnosis requires an MRI of the lumbar region L1-L-5. Steroidal injections rarely provide more than a few hours relief. Fortunately the episodes are usually self-limiting.A physical therapy program is usually the first step. And avoiding all lifting. In a worst case a laminectomy should be considered.
