Ever since Hillary Clinton’s Benghazi testimony was delayed by a fall and a concussion, the state of her health has been questioned by her critics and treated by here defenders as a medical subset of the vast right-wing conspiracy. She attempted to make light of new questions being raised, in part from simple observation of her recent behavior by opening a jar of pickles on Jimmy Kimmel’s show Monday night and having him feel her pulse.

Team Clinton would have everyone believe this is just another far-right conspiracy theory but incidents indicating she might be in a real pickle over her health keep popping up. For example, on July 21, Hillary was filmed talking to reporters when she began a bizarre head-bobbing episode followed by a strange response to reporters’ questions about her VP choices. As The Hill reported:

Hillary Clinton seemed taken aback and sought to change the subject when reporters asked whether she has spoken with Sen. Elizabeth Warren (D-Mass.) about being her running mate.

The presumptive Democratic presidential nominee was speaking to reporters as she bought a cold tea at Uprising Muffin Company in Washington, D.C.'s Shaw neighborhood Friday.

“Have you talked about vice presidential possibilities with Sen. Warren?” one reporter is heard asking in a video tweeted by CBS reporter Hannah Chanpong.

The presumptive Democratic nominee exaggeratedly bobs her head, widens her eyes and then laughs when a few reporters repeat the question.

“You guys have got to try the cold chai,” Clinton responded, holding up her tea.

This bizarre episode might be chalked up by some as campaign fatigue but this was not just some slip of the tongue. It may also be the tip of a health issue iceberg: In May, 2011 Hillary Clinton fell boarding her aircraft during a trip to Yemen. A video of the event recorded her fall As the Telegraph reported:

The US Secretary of State was boarding a plane to head to Oman when she tripped over a step and ended up on the floor.

Mrs. Clinton was visiting Yemen, with the declared aim of helping the country cope with a growing al-Qaeda threat through political, social and economic reforms, was unhurt and was quickly helped to her feet to continue her journey.

A photo that went viral and that was later published by Reuters and Getty shows Hillary being helped up the stairs of a home during a campaign stop in South Carolina in February:

Hillary Clinton needed to be physically helped up a moderate flight of stairs by her team of staffers and handlers, according to campaign-trail photos that made the rounds on the Internet Sunday.

Reuters and Getty photographs captured Hillary Clinton, 68, struggling to make it up the stairs, either as a result of her fragile body or perhaps because her well-documented brain injuries make it harder for her to transport herself through daily life activities. The photos gained wide circulation on the Internet Sunday. The photos were taken in February as Clinton was campaigning in South Carolina.

Perhaps this explains why Hillary’s campaign appearances are carefully choreographed, and why she avoids press conferences. Another head-bobbing incident would be harder to explain than Donald Trump’s hair. Should Hillary’s health be campaign issue. Investor’s Business Daily in 2014 said it should, starting with the bobbing and weaving around the original “Benghazi bump”:

After Bill Clinton contradicted State Department claims about Hillary's health with news of a six-month rehab, her fitness should be as much of an issue as Sarah Palin's baby and John McCain's age…

During the week of Dec. 9, 2012, Secretary of State Clinton is said to have fainted at home, hitting her head as she fell. Clinton was diagnosed with a concussion, the New York Times reported on Dec. 13, with a State Department official saying the concussion "was not severe."

On Dec. 15, State Department spokesman Philippe Reines released this statement on the concussion:

"While suffering from a stomach virus, Secretary Clinton became dehydrated and fainted, sustaining a concussion. She has been recovering at home and will continue to be monitored regularly by her doctors."

On Jan. 3, 2013, Clinton is released from the hospital and returns to work where she is presented with a football helmet by State Department staff. Spokeswoman Victoria Nuland explains that "the secretary is going to be wearing the glasses instead of her contacts for some period of time because of lingering issues that stemmed from her concussion."

After that, the administration took the usual "nothing to see here, so let's move on" position.

Then on May 14, while defending his wife from Rove's remarks on whether this was more than a head bump, Bill Clinton revealed that his wife's injury "required six months of very serious work to get over." This contradicted news and State Department accounts. The question is why this was not revealed earlier.

Indeed there are many questions about Hillary’s health, past, present, and future that need to be answered, starting with the obfuscation that continues to this day, The “Fox News Medical A-Team” recently addressed the issue on Hannity:

Dr. Marc Seigel said "the public has a right to know" and speculated on what the issue could be but was more interested in previous spills and a concussion she had in 2012.

"I think the public has a right to know," Seigel said. "We're talking in 2008, Sean, I looked over a thousand pages of John McCain's records because of a melanoma he had 10 years ago. What about Hillary? In 2009, a severe fall. She breaks her elbow. In 2011, she boards a plane, falls. In 2012 she has a severe concussion which Bill Clinton says took her six months to recover from.

"Then she ends up with a blood-clot in the brain and a lifetime of blood thinners," Seigel said. "Just that point alone -- if she's prone to falling, you can see from that picture up there that it looked like she can barely get upstairs without two people carrying her. Guess what if she falls and hits her head? She'll get a blood-clot."

"I want to know what her neurological records show," he added…

"I think a traumatic brain injury with symptoms down the road is very, very likely here especially since she had a blood-clot on her brain. As David mentioned that could lead to a seizure problem. Someone is carrying a [diazepam] pen that you'd use in case of a seizure, a Valium pen, that makes me wonder about that," Dr. Seigel said.

Indeed, when a member of Clinton’s entourage is seen carrying a Valium pen in case of a seizure, it should be a concern and an issue every bit as much as Reagan’s age and McCain’s war experiences.
