Sources close to Hulk Hogan tell TMZ the wrestling legend was taken to the hospital today because of "excruciating back pain."
We're told Hogan -- who has had several back surgeries throughout the years -- has had trouble the past few days and woke up this morning unable to get out of bed.
His girlfriend called the ambulance and, we're told, he was taken to a local hospital in Clearwater, FL.
Sources tell TMZ Hogan is still in the hospital where tests are being run.
UPDATE: Hulk took the time to post a video from hospital room. Intestinal fortitude, brutha!
