Dr. Michael Russo, who performed Miller's gastric sleeve surgery last year, told ET that he believed Miller’s severe back pain stemmed from hypothyroidism, which occurred after she stopped taking one of her thyroid medications.
"Her hypothyroidism got so severe she had an assortment of symptoms. Most dramatic is severe muscle and bone pain in her back, shoulders, arms and legs," Dr. Russo shared. "When Abby first went to the ER, she was almost unable to move [her] arms and legs and was having trouble getting out of bed. She had numbing and tingling in her hands and feet. She couldn't even hold a spoon in her hand."
“If left untreated it's been reported people can become comatose," he added. "This is a serious medical concern."
Abby Lee Miller Spotted Getting Pampered After Prison!
Miller's spinal surgery comes less than a month after the 51-year-old dance instructor was released from the Federal Correctional Complex in Victorville, California, where she served 259 days of a 366-day sentence after pleading guilty to bankruptcy fraud in June 2016.
Following her release, she was transferred to a halfway house in Long Beach for the remainder of her sentence.
