Hi volans,
Welcome to the NeuroTalk Support Groups.

If I had that happening to me I'd have to wonder about nerve entrapment or compression particularly of both or either the genitofemoral nerve and sciatic nerve.

Have you been to see a good physiotherapist and talked with them about what's been happening?

Also there are some good spine/nerve maps around. Might be worth checking those out to see if you can garner any info from them.

I'm sorry to read about your pain and situation. I hope you find some help soon,
take care.
