Less than a month after suffering a massive brain hemorrhage, Bret Michaels is in the midst of another health crisis. After experiencing numbness on the left side of his body earlier this week, the rocker was rushed to the hospital where it was found that he had experienced a transient ischemic attack, or small warning stroke. With further testing, doctors also discovered that Bret had a hole in his heart. Neither ailment is believed to be related to his subarachnoid hemorrhage on April 21. Despite the shocking setback, the former Poison front man is still in good spirits. "Without a doubt, he is very determined to get healthy and make a 100 percent recovery," neurosurgeon Dr. Joseph Zabramski said on Bret’s website. The driven Celebrity Apprentice contestant even is still planning on attending the season finale of Donald Trump’s NBC hit competition show on May 23. "As far as I know, Bret will be there unless his doctors tell him otherwise," a rep for the singer says.
