Shane,
Welcome to the board. I'm sorry you are dealing w/ back pain.... especially sciatica! I have that - it can be miserable!
Things that work for me for the sciatic nerve pain - trying not to stay in the same position for long lengths of time. That's usually what causes this pain to flare for me.
I take nerve medication that helps somewhat. I've used an anti-inflammatory. I have lidocaine patches that I use that help numb the area a bit, and that can help. I've used heat (heating pad) or ice before.
This sounds crazy (but when you are in pain - you are desperate and will do anything!).... but I find "counter-pressure" works well when the pain is at it's worst. I've had my husband do deep tissue massage.... and I've even used a tennis ball (or something similar) to give that counter-pressure. Sometimes, it will give just enough relief to make it tolerable.
That's all I can think of right now. Maybe others will have some other suggestions. I AM sorry you are suffering w/ this! But I'm glad you found your way to the board.... .and hope to see you more.
Take care -- Tina
