U.S. Secretary of State Hillary Clinton remains hospitalized in New York, where she is being treated for a blood clot in her head, doctors said.

The clot is located between the brain and skull in a vein near the right ear, doctors said.

Clinton did not have a stroke and did not sustain neurological damage, specialists said.

The secretary of state was hospitalized on Sunday after her doctors discovered a blood clot during a routine medical examination.

Clinton's blood clot is related to a concussion she sustained after fainting on Dec. 15.

The 65-year-old Clinton has kept up a blistering pace as the top U.S. diplomat, undertaking numerous foreign trips.

The secretary of state's fainting spell was blamed on a stomach illness that caused her to become dehydrated and weak.

Clinton cancelled all her foreign trips and her appearance before Congress to discuss the attack on the U.S. Consulate in Benghazi, Libya, on Sept. 11 in the wake of her illness.

The former first lady and senator said she would not stay on as secretary of state in President Barack Obama's second term.

Clinton has also denied reports that she plans to run for president in 2016.

Obama has nominated Massachusetts Sen. John Kerry to succeed Clinton as secretary of state. EFE
