Sciatica/Scaroilliac pain?

[sayerville]

About 3 weeks ago I twisted whilst cleaning and had a really painful back for about a week or so, that went but now I have what feels like really bad nerve pain, but this comes from my groin and spreads down my right leg. Sometimes it's excruciating and I can't even put my foot to the floor and weight bear.
This cleared up whilst in Spain for 4 days last week, maybe I was doing more moving around, maybe the heat I have no idea, I come back and it's back again. Mainly on getting out of bed or after sitting. When walking it is weird , no pain bit sometimes my leg will ache.
Anyone else had this kind of issue, I am thinking maybe pinched nerve in my hip after twisting.

I have almost exactly this. Mine starts in my bum cheek and refers to different places. Sometimes feels like my leg might fall off.

Exercise is the best for it. Hurts afterwards but always get relief after that. I'm trying sleeping with a pillow between my knees at the min which is helping

I suffer from nerve entrapment as Parton my cerebral palsy and the pain is similar to your description. So hard to find a cause, but so easy to do
I have a shaped pillow between my knees and an orthopaedic pillow
You could also try a Mini tens machine( around £20) for relief

I did read about the pillow trick which I have tried for the last two nights, i think it's helping.
Did any of you get a diagnosis what causes the pain, like a trapped nerve etc?

I had physio for a bit which didn't help much, I find it hard to do exercises properly at home. I work in a nursery so it's most likely because I pick children up all the time and have small furniture so my knees are always higher than my pelvis. It seems to be caused by a weakness in the muscles which is improved by exercise. I also had sp during pregnancy so there is a weakness in my pelvis anyway
