Gymnast McKayla Maroney Rushes to Emergency Room in 'Severe Pain'

McKayla Maroney hit up her Instagram Stories first thing on Thursday morning as she provided her over 1 million followers with a real-time update on her medical situation. The star knew she had to describe what was going on after first posting a photo of her trip to the Benjamin & Carmela Du Emergency Pavilion in Orange County.

"Tuesday I was throwing up all day, with severe pain in my back and stomach," Maroney told her fans while showing herself lying in a hospital bed.

Looking quite beautiful, despite an obvious night of pain and suffering, Maroney shared with fans that doctors were able to locate the source of her medical emergency after being admitted to the E.R.

"Had to come to the ER at 3am because pain kept getting worse, and I couldnt' stop throwing up. Just got by CT Scan back. I have a few kidney stones."

For those who have never had them, kidney stones can be a surprisingly painful situation that needs to be treated ASAP.

According to the Mayo Clinic, kidney stones are, "hard deposits made of minerals and salts that form inside your kidneys."

Affecting the urinary tract, kidney stones are formed when the urine becomes concentrated, allowing minerals to crystallize and stick together. They can be caused by a myriad of things, including diet, exercise, and supplements that are consumed.

Unfortunately, the most common way to get rid of kidney stones is for them to pass naturally, which can be a very painful process. Sometimes the stones can be broken up during medical treatment, allowing smaller pieces to be passed easier, however, if the patient is unable to pass them on their own surgery is sometimes needed.

Hopefully, the process is easy for Maroney so that she can start her road to recovery.
