You're probably on the mountain right now - sorry to hear it. White is a 14'r of course, but the down slope and then the up slope, etc., are a painful way to acclimate for Whitney. I'd recommend spending more time on the Whitney trail itself, Lone pine lake overnight, Outpost overnight, TC, etc., or hanging out at the trail head at Langley is about 10,000 feet and a fine place to kick it back and get the blood cells to open up.
