Pain in the sacroiliac (SI) joint can make sitting, standing, or even rolling over in bed uncomfortable. Some people feel it in their lower back, others more in the hips. When rest, stretching, or over-the-counter meds aren’t cutting it, two common options come up: steroid injections or physical therapy. Both have their place. Neither is perfect.
Steroid Injections
A steroid injection goes straight into the SI joint to calm inflammation. The idea is simple: reduce swelling in the joint, and the pain should drop. It’s done with a needle, sometimes using imaging to guide the placement. Relief can be quick and, for some, almost overnight.
Pros of Injections
- Fast relief for many people
- Helps confirm the SI joint is the real problem
- Office procedure, done fairly quickly
Cons of Injections
- Relief doesn’t always last (weeks to months)
- Doesn’t fix weak muscles or poor movement patterns
- Can’t be repeated endlessly without risks
The Basics of Physical Therapy
PT focuses on movement, strength, and stability around the SI joint. Therapists often use exercises, stretches, and sometimes hands-on techniques to help calm pain and prevent it from coming back. Relief takes longer, but it builds a foundation.
Pros of Physical Therapy
- Targets the root cause, not just symptoms
- Builds strength and stability that lasts
- No medication side effects
Cons of Physical Therapy
- Slower relief compared to injections
- Requires consistency and effort
- Progress isn’t always linear
What Patients Usually Ask
A common question is whether injections or therapy “work better.” The truth is, they do different things. Injections bring faster pain relief but don’t solve the underlying weakness or mechanics. Therapy takes longer but builds protection against flare-ups. Another question is about safety. Injections are generally safe, but can’t be repeated forever. PT is very safe but requires showing up and putting in the work. Knowing what matters most to you, speed or long-term stability, usually guides the choice.
Which One Makes More Sense?
It depends. If it's cutting and searing pain, an injection will relieve it quickly so that you can move once again. If it's bothersome or keeps coming and going and flaring up, PT would likely be better because it will make your body strong and will make it less likely that you will have another flare-up. Some people choose to do both an injection to calm things out and therapy to make things strong again.
