Nothing to be sorry about. My only defense for my crummy writing is I messed up my back big time a few days ago - and between that, my prescription pain killers, and my fourth glass of Scotch, well, I couldn't even feel the keyboard. Hey, when they say don't mix alcohol with Vicodin, believe 'em.
I've had back problems in the past.
And most of the other joints at one time or another.
I hope it's nothing serious.
Don't let the pain killers fool you into thinking you can do things you know you shouldn't.
