Lindsay Lohan's estranged and equally troubled father Michael Lohan was taken back to the hospital early Friday morning after experiencing chest pains.
MiLo was transferred from a rehab facility in Palm Beach, Fla., after doctors found blood clots and put him on medication to try and break them up.
Doctors feel they don't need to perform surgery, but they want to keep in the hospital for a couple of days to make sure Mike's medication works.
This is the second time in less than two months Lohan has been hospitalized for recurring heart problems. He collapsed at an AA meeting the last time.
He had surgery to repair a blockage back on December 5.
Lohan is due to be released from rehab on March 16. It's unclear whether that will be pushed back due to this and previous hospital stays.
We wish him a fast recovery in any case.
