The Fantastic Four star wasn't feeling so fantastic when she woke up with a swollen ankle on Friday morning (22Jun12) and she took to Twitter.com to share her pain with fans.
Posting a picture of her bruising, she wrote, "Swollen ankle - a plate fell on my ankle last night... Hurts."
Alba later posted a photo of her ankle being X-rayed.
Earlier this week (beg18Jun12), the pretty actress posted the first shots from the set of the action film Machete Kills, in which she posed with castmates like Danny Trejo.
