lower back pain/sciatic nerve

My daily or nightly routine,  hence me being up at this time, is I awake usualy every two hours or so at the mo. where my lower left, back due to the sciatic nerve is very painful, no matter how I move position it does not go, only if I get up it subsides, I usually feel hot so sit in the dark with Adel 21 (music) playing with the back door open to cool me down, I then sitting in my chair, place an iceback, at bottom lower back area, which also gives relief. my neck too is tender. sometimes if I need to have a wee that also gives some relief. Now feeling a lot better I will take a pain killer and go back to bed with my icepack So I now bid you Goodnight!
