Doctors for Secretary of State Hillary ClintonHillary Diane Rodham ClintonGrassley blasts Democrats over unwillingness to probe Clinton GOP lawmakers cite new allegations of political bias in FBI Top intel Dem: Trump Jr. refused to answer questions about Trump Tower discussions with father MORE said Monday that the blood clot they discovered during a follow-up exam is located between her brain and skull, behind her right ear.

The statement came a day after physicians announced Clinton had been hospitalized because of the blood clot. The clot stems from a concussion the secretary suffered earlier in December.

"In the course of a routine follow-up MRI on Sunday, the scan revealed that a right transverse sinus venous thrombosis had formed. This is a clot in the vein that is situated in the space between the brain and the skull behind the right ear. It did not result in a stroke, or neurological damage," Dr. Lisa Bardack and Dr. Gigi El Bayoumi said in a statement.

Clinton is being treated with blood thinners, the doctors said. 

"To help dissolve this clot, her medical team began treating the secretary with blood thinners. She will be released once the medication dose has been established," Bardack and Bayoumi's statement said. "In all other aspects of her recovery, the secretary is making excellent progress and we are confident she will make a full recovery. She is in good spirits, engaging with her doctors, her family, and her staff."

Doctors said on Sunday that Clinton is receiving treatment at Presbyterian Hospital in New York.

Clinton suffered a concussion after fainting while she was sick with a stomach virus. When she suffered the concussion, doctors said Clinton would spend her recovery at home as doctors monitored her condition.

It's not the first time Clinton suffered a blood clot. In 1998 doctors discovered a clot behind the then-first lady's knee.
