FUCK!! I think I've hurt my hand and I have to perform (guitar) in less than a week!

OK, I’m in a bit of a panic right now. I’m playing the lead part in Steve Reich’s Electric Counterpoint and I may have worked my hand too hard practicing last night, because last night and all day today I have felt a sensitivity in my hand (palm, pinky side) and in my elbow. I may have really done some damage and I’m not sure what to do.
The performance date is set for Wed. and there are 14 other musicians and a conducter counting on me and I’m really fucking angry at my own stupidy for working my hand that much last night. I should have known my limitations and I can’t even find a scapegoat to kick because it’s my own stupid fault.

Anyone know how to make a hand better really quickly? please?

Well… sounds like you may have pinched your median nerve.
I would suggest shortening your guitar strap and make sure you arent bending your wrist to much.
Good Luck on the gig.

Naughty lad, you already posted this in GQ. The mods take a dim view of this.

Yes, we do take a dim view of crossposting. So I’m closing this thread.
