Blackouts & Blood Clots! Hillary Clinton's Secret Multiple Sclerosis Crisis REVEALED

Desperate to win the White House, Hillary Clinton is keeping a shocking medical condition from voters — she's secretly battling deadly multiple sclerosis, RadarOnline.com has learned.

In a bombshell exclusive, multiple sources told RadarOnline.com that the 68-year-old former first lady is in the early stages of the incurable nerve-savaging disease, which saps victims' energy, wrecks their balance, triggers falls and often causes vision problems.

Photos show the Democratic presidential candidate wearing glasses with a prism — a feature designed to fix double vision, a symptom of the disease.

After suffering a series of falls and repeatedly being photographed struggling to stand and walk, sources said, Hillary is terrified her medical situation will doom her presidential dreams!

"She's been working with her staff to keep the medical drama under wraps, and she's doing her best to deal with it," an informant told RadarOnline.com.

Multiple sclerosis, an autoimmune disease, afflicts 2.5 million people worldwide and can affect the brain, spinal cord and other areas of the body.

Early symptoms of the disease include weakness, tingling, numbness and blurred vision. Thinking problems and urinary troubles can also result, as can muscle stiffness.

Loss of balance can be another symptom — and Hillary has a history of blackouts, falls, memory loss, vision problems and collapses dating back at least 10 years.

In December 2012, she suffered a concussion from a fall requiring her to be hospitalized for three days.

GOP strategist Karl Rove later ignited a firestorm when he asserted that Hillary had suffered brain damage from that fall.

Hillary also suffered two deep-vein blood clots — one in 1998 and the other in 2009 — and she still takes the blood thinner Coumadin, as well as antihistamines, which can lead to weight gain.

Chillingly, New York internist Dr. Stuart Fischer said the pressures of the presidency could "worsen her neurological problems quickly."

Sources also accuse Hillary of going on booze binges following troubles over emails she sent and received on a private email server while secretary of state.

They claim boozing will worsen her symptoms of depression.

Meanwhile, Hillary has been putting on a brave face publicly, trying to hide her MS from voters.

"But behind the scene she seems exhausted, dazed and confused at times," an insider said.

The source claimed that Hillary's most trusted aide, Huma Abedin, sleeps with her in hotel rooms "in case there's a medical emergency."

Sources also warned that Hillary won't be able to keep her MS under wraps from the public much longer.

"Hillary has had a problem telling the truth her whole life," the source said. "She's always exaggerated how good or how bad things are to suit whatever image she wants to project on any given day."
