Mike Skinner was treated by St John Ambulance
Singer Mike Skinner needed medical treatment after he "crowdsurfed" at a concert in Cambridge.
The 30-year-old, who performs under the name The Streets, appeared at Cambridge Corn Exchange on Tuesday.
He wrote in his blog that he jumped into the crowd and was punched and scratched, and woke up the next day in "unbelievable pain".
St John Ambulance treated the singer at the scene, before calling an ambulance to provide further medical attention.
On social networking website MySpace, Skinner said: "Seriously never known pain like it and I broke both my arms when I was younger, hardly noticing it. Some kind of tendonitis, cramping and general bodily bashing."
The Streets are on a tour of the country before playing dates in Australia.
