I need help

I'll keep it short n sweet. I didn't get a lot of sleep last night and I'm having a horrible flare. And I mean terrible. One of the worst I've ever experienced myself. The pain is almost unbearable. But here's the catch, I'm busy all day and won't be home until later tonight. Anyone have quick solutions to the pain when you don't have immediate access to your typical pain relief creams and pills and such? I have specifically this horrible nerve pain going from my upper arm all the way down the side into my hand and pinky finger. I have pain in my thighs, back of my arms, calves, and knees. And it's so bad I'm having a hard time breathing at the moment. Any massage or pain relief suggestions just to get me thru the day until I can get home?
