Hillary Clinton underwent surgery to treat an ear infection after a course of antibiotics and steroids earlier this year, her doctor has revealed.
The Hillary campaign has published part of her medical history for this year after she was diagnosed with pneumonia.
But instead of quashing speculation surrounding her health, it has raised questions among her critics about whether Clinton is fit enough to lead as president.
Part of the letter, written by Clinton's physician Lisa Bardack, reads,
In January 2016, Mrs Clinton developed symptoms of sinusitis and an ear infection, which was treated with antibiotics and steroids. Over the ensuing few weeks, she noted progressive pain in her left ear despite treatment, and subsequently was evaluated by her ENT physician. this evaluation confirmed a sinus and ear infection, with increased fluid in her left ear. To alleviate her symptoms, a myringotomy tube was placed in her left ear in January of 2016. After the tube was placed, Mrs Clinton had significant improvement in her symptoms.
A myringotomy is a surgical incision in the eardrum to relieve pressure or fluid.
She said this was followed up by a CT scan of her brain and sinuses in March 2016 and confirmed the scan "showed no abnormalities of the brain and mild chronic sinusitis."
The presidential candidate was symptom-free for the next six months.
Then came the medical episode on September 11.
Clinton was attending a 9/11 memorial in New York City when she became "overheated" and left the service after an hour or so, a spokesperson said at the time.
A video showed the moment she collapsed as she was being led away to a car.
It was later revealed Clinton had been suffering from pneumonia.
But despite her string of medical issues, the physician has stressed Clinton is still "fit" to serve as president.
The letter concludes,
My overall impression is that Mrs Clinton has remained healthy and has not developed new medical conditions this year other than a sinus and ear infection and her recently diagnosed pneumonia. She is recovering well with antibiotics and rest. She continues to remain healthy and fit to serve as President of the United States.
