She returned to her home in Chappaqua, where she remained for the rest of the day.

Late Sunday evening, Clinton spokesman Nick Merrill said she would not be traveling to California on Monday or Tuesday for campaign events that she had scheduled there.

Clinton's Known Health History

Clinton, like Trump, has not released her medical records in full detail.

Last July, her campaign released a letter from Bardack, summarizing her current health status, and noting that she had hypothyroidism and suffered from seasonal pollen allergies.

It also noted that she had been treated for a deep vein thrombosis -- \"when a blood clot (thrombus) forms in one or more of the deep veins in your body,\" according to the Mayo Clinic -- in 1998 and another in 2009.

She also suffered from an elbow fracture in 2009.

\"She is excellent physical condition and fit to serve as President of the United States,\" Bardack concluded in the statement.

In 2012, when she was secretary of state, Clinton \"while suffering from a stomach virus ... became dehydrated and fainted, sustaining a concussion,\" according to Philippe Reines, a state department spokesman, in a statement released at the time. Follow-up exams found a blood clot, forcing her to seek treatment in a New York hospital.

Bardack's letter released by the campaign last summer noted that as a result of the concussion she suffered from double-vision, which was treated with special glasses before it resolved itself \"within two months.\"

The doctor's letter said that the clot, called a transverse sinus venous thrombosis, was treated with anti-coagulants and that follow-up tests conducted in 2013 \"revealed complete resolution of the effects of the concussion as well as total dissolution of the thrombosis.\"

It also stated that Clinton, \"tested negative for all clotting disorders,\" but that doctors had decided to continue a daily regimen of anti-coagulants as a precaution.
