Struggling with SI joint pain, glute burning and rebound after pregabalin—any similar experiences?

I’d really appreciate hearing from anyone who’s had something similar.

I had steroid injections into my SI joint and L5/S1 about 4 months ago and since then have had ongoing nerve irritation, especially burning pain in the glutes (worse at night and early morning).

I took pregabalin for a month but had to stop due to dizziness. I’m now about 3 weeks off it and seem to be having rebound nerve pain that’s actually worse at times, especially at night.

I’ve been trying to manage with gentle movement, pacing, ice/heat etc. Some days it feels like it’s easing, then I get a flare (often early morning around 3–5am).

I’m now considering starting gabapentin but feel quite anxious about side effects and withdrawal after my experience with pregabalin.

Has anyone else had:
• Nerve irritation after SI joint injections?
• Worsening pain after stopping pregabalin?
• Early morning flares like this?

And did gabapentin help you—or not?

It’s been quite exhausting and a bit demoralising, so it would really help to hear others’ experiences.
