Kirsten Storms is opening up about recently undergoing brain surgery.

Two days after the General Hospital star, 37, first shared that she had gotten surgery to drain and remove “a very large cyst that had split into two,” the actress shared additional details about her health and what led to the operation.

“First, thank you for all of the well wishes I’ve received over the last few days,” she wrote on Sunday, noting that she’s experienced “random health issues” for several years now, which she disregarded at the time as being side effects to “my medications or just something I was experiencing due to age.”

“When I went to get an MRI for some severe neck pain I have been experiencing for the last few months (I assumed this neck pain was also causing my frequent ‘migraines’) my amazingly thorough orthopedist ordered an MRI of my head just to be on the ‘safe side’ – even though that isn’t his area of expertise,” Storms added, calling him “truly a great doctor.”
