LeAnn Rimes is recovering after undergoing mystery surgery to correct a jaw issue.
The singer took to Twitter on Saturday to tell followers about her medical woes, but refused to go into detail.
She wrote, "I had minor surgery this week and I've been in SO much pain it's not even funny... Nothing major just annoying! Pain pain go away!!!!!! When it's mouth pain and jaw pain it makes your whole head pound! YUCK."
