Arsenal midfielder Freddie Ljungberg will resume training next week after a brain scan to determine the cause of his migraines showed nothing wrong.
Ljungberg, 27, has been out of action for the last 10 days after a series of severe migraines and has missed the Gunners' last two matches.
"I went to see a specialist on Thursday and had a brain scan, the result of which was normal," said Ljungberg.
"They confirmed I have been suffering from a severe migraine attack."
He added: "The doctor felt the second one occurred because I pushed myself to train too soon after the first migraine.
"If I had rested for longer I wouldn't have had the second attack. I have been told to rest for the next few days and hope to be back in training next week."
