Ananova:

The oldest member of pop group Hanson is being treated in hospital for a blood clot in his right arm brought about by strumming his guitar too much.

Isaac Hanson, 23, had a venous clot, or thrombo-embolism, said his publicist Jill Fritzo in New York.

"He'll be in the hospital for a few days," she said. "He's uncomfortable, obviously, but he'll be fine."

The Hanson trio, which includes brothers Taylor and Zac, had its biggest hit in 1997 with MMMBop.

They recently played Carnegie Hall in New York as the final stop on their acoustic tour.

They have started their own record label, 3CG records, and plan to release a new album in March.
