A young builder has had his life turned upside down after being struck by a severe headache, which spiralled into a life-threatening condition.

Joel King, 28, was diagnosed with a colloid cyst, a benign tumour in his brain, which led to a stroke.

The keen hunter was left with cortical blindness (tunnel vision), meaning he can now only see 10-15% of what he could.

Joel was a builder and loved hunting every chance he got, but now even the simplest routines like driving have been stripped away.

‘My head feels like it’s in a vice’

King‘s partner, Abby Holliday, 27, told the Herald his memory of the day things unravelled remained fuzzy.

“It was Valentine’s Day that he came home from work with a bit of a headache, and we headed out for the night to go camping, just sort of thinking nothing of it,” she said.

By midday the next day, the headache became “pretty gnarly”.

After a sleepless night in pain, the pair thought he was suffering from a migraine and sought advice from Healthline.

King’s fingers began to tingle, so the pair rushed to a 24-hour care clinic.

After getting some fresh air, King collapsed and was later struck with a seizure-like episode because of the pressure buildup in his head.

King was stiff, muddled and agitated.

‘If they don’t do something about it, Joel will die’

King was taken in an ambulance to hospital and underwent a CT scan, which showed his ventricles were full of fluid.

“Your ventricles make the spinal fluid that drains naturally through the body, and they were full and incredibly enlarged.”

She said they didn’t know why they were enlarged.

“All they knew at that point is if they don’t do something about it, Joel will die,” Holliday said.

King was then taken for an emergency external ventricular drain procedure.

The morning after the surgery, in an MRI, doctors discovered King had a colloid cyst blocking his ventricle drainage.

Diagnosis and vision problems

Holliday said she understands many people who have a colloid cyst aren’t made aware of it until they have a knock on the head or find it by chance during a CT.

“Joel’s was never known about, had sudden symptoms, and then ended up being life-saving surgery out of the blue,” she said.

After a successful surgery to remove the cyst, he was moved to the Neuro progressive care unit.

It was discovered something was “really wrong” with King’s vision because he wasn’t opening his eyes.

Doctors looked back over a previous MRI, and they found he had a stroke.

“It’s the first time that we found out Joel had a stroke... like six days later.

“It was so much pressure on the brain it sort of stopped the blood flow to the optical lobe, so where his vision box is in his brain, for long enough obviously to cause some damage,” she said.

A couple of weeks later, he moved across to Burwood in the Stroke Care unit in Canterbury, where he recovered well.

‘You’ll never drive again’: Road to a new normal

King was told the damage from the stroke was significant. After weeks in rehabilitation, he was finally discharged on April 1.

Holliday said they were told by an eye specialist he would never drive again and the chances of him returning to his job would be “super slim”.

King said he’s struggling to come to terms with everything.

“Finding the new norm ... I still want to be like normal ... I want to be able to do everything that everyone else can,” he said.

Holliday said King used to hunt every minute he wasn’t working, and they are working towards finding a new way for him to do this.

“We can still do that eventually, but it is going to look very different.”

Since his diagnosis, King’s friends have stepped up and taken him to do “normal bloke stuff”.

“Your life literally gets completely turned upside down and some things taken away from you, and you really do have to fight and work to get them back,” Holliday said.
