British rapper Wretch 32 is recovering from a swollen foot.

The Don't Go hitmaker, real name Jermaine Scott Sinclair, was in agony while performing at England's Reading and Leeds Festival over the weekend (23-25Aug13) after suffering a mystery injury days earlier.

He tells Britain's Daily Star newspaper, "When I came off the stage last week my trainer felt really tight on my left foot. I took it off and it was mad swollen and it kinda (sic) hurts. I'll be cool though. I'll have a little drink to numb it up."

The rapper is set to release his upcoming album, Growing Over Life, later this year (13).
