Miley Cyrus has spoken out about her recent stay in the hospital. The 21-year-old singer spoke to Ryan Seacrest on Monday, and told the host she is on the mend and ready to perform. "I'm doing good, I'm much better," she says. "I'm happy to be getting back on the road." Cyrus was admitted to a Kansas City hospital on April 15 after she suffered a severe allergic reaction to antibiotics. Her stay forced her to cancel several U.S. stops on her Bangerz tour, and she plans to make up the shows in August. She was released from the hospital on April 25. "[Some] people [got] mad at me for bailing," she continues. "There is no part of me that wants to lay in bed and not be on stage. I wanted to be on the tour so bad. I was begging the doctor to let me out just to go do the show. But there was no way." The singer says one unexpected side effect of her hospital stay was "way too much online shopping." "I was just crying because I was so bored!" she exclaims. "Whatever they had me on to make me not in pain I made some very questionable choices on what I bought [online]. I'm like, 'I do not know what this hot pink miniskirt is that I bought in the hospital." Cyrus says there should be no long-term health effects from her allergic reaction, and is just happy to resume her tour. "The only good part about this whole thing is I feel like I get to go on another tour," the singer says of the rescheduled dates. The singer departs the U.S. on Wednesday, and kicks off the European leg of her tour Friday in Amsterdam.
