Everything's bigger in Texas ... including Bette Midler's big toe, which is now sporting a huge green bandage thanks to a pedicure gone horribly, horribly wrong.
Bette tweeted a pic of her aching piggie majorus a few days ago, adding ... "My New York toes don't love Texas cowboy boots."
But TMZ has learned the problem wasn't boots -- sources close to Bette tell us it was an ingrown toenail caused by a clueless manicurist who recently gave her a bad pedi.
Bette was in Dallas to make the keynote speech at the Jewish Family Service women's luncheon -- and we're told the pain was just too much, so she had the ingrown toenail removed ... (clap clap clap) deep in the heart of Texas.
Ironically, Bette's speech was about going green.
