YES!!! that is EXACTLY what it feels like. DP looks at me like i am insane when i say my butt hurts, the pain is around there and my hip and then my lower back. Sometimes when the sharp pains happen i feel them all the way down. I almost feel myself falling over from the pain.

I will be definitely seeing about it as id hate for it to turn into something more serious.
If its sciatic pain, you can do something at home to fix it. You should be able to find a 'knot' kinda in the middle of your bum cheek. Get your DP or a friend to massage it, cos this is where the pain is coming from. When my DH gets sciatica, i find it easier if he lays on his tummy, and i rest my elbow on the tight muscle bit, and put pressure down. (my hands hurt, but elbow works). It helps to release the tension and then the referred pain.

If you can see a physio, even better! but some home massage may help too

If you google images of the sciatic nerve, or look at an anatomy book you can see where the nerve usually goes.

take care,
