The diagnosis is in for pop star Austin Mahone, who was
rushed to the hospital Thursday
after feeling ill.
The teen pop star "was admitted to the hospital with 104 temperature and is being treated for a blood clot and extreme inflammation in his throat, as well as severe dehydration," his rep tells PEOPLE.
Mahone, 17, previously posted a photo of himself in his hospital gown on Instagram, captioning the image, "I've never felt so bad."
Plans to postpone
Mahone's tour to 2014 still stand, as an official statement confirmed Thursday that he "is now on strict doctor's orders to stay on rest."
Love and support for the "What About Love" crooner from fans through social media channels has stayed strong, with the hashtag #prayforaustin continuing to trend.
