Former England Test spinner Shaun Udal says he has the "toughest test of his life" ahead after being diagnosed with Parkinson's.
The ex-Hampshire and Middlesex player, 50, confirmed he was living with the illness on social media, prompting numerous messages of support.
"I've just got to get on with it," Udal told BBC Radio Solent.
"I can't think negatively and get downbeat because it's going to affect my chances of recovery and progress."
He added: "It's the toughest test, but I'll face it head on, tackle it and with the support of friends and family we'll keep it under control."
In addition to his Test exploits, Farnborough-born Udal also played 10 one-day internationals.
Parkinson's is a progressive neurological condition, which according to the condition's support website 'causes problems in the brain which get worse over time'.
Having called time on his professional career in 2010, a recurring issue led to a concerning revelation which would change his future indefinitely.
"It's been nagging away at me a couple of years," Udal added. "I had a neck operation about three and a bit years back which was a success thanks to the Professional Cricketers Association for sorting, but for a period of time of about a year afterwards I was constantly getting arm pains and shakes and stuff.
"The scans kept coming back and they were saying there was a vertebrae pushing down on my nervous system which is making my arm shake - but I knew it wasn't right, you know your body better than anyone else.
"Eventually after asking and pushing for more scans and detailed things to happen, I had a brain scan about January time and got the results back, which unfortunately showed that Parkinson's was the issue.
"I found out six weeks ago, it's a bit of a shock but there's always someone else worse off and you have to cope with it and move on."
Udal's cricketing career carried all the hallmarks of a character who would face a challenge head on, having grafted at first-class level for 21 years.
He represented England in four Tests, and it was his willingness to keep fighting which saw him recalled in 2005 - 11 years after his previous appearance.
Perhaps his finest hour came in Mumbai, India - when he snared Sachin Tendulkar among others in a four-wicket haul to help the injury-hit tourists to a 212-run Test win - the first in the country for 21 years.
He will need all of that dogged determination now to keep check of the debilitating illness.
"There's been moments where I get agitated, worried and concerns because my speech gets a bit slurred, my arm suddenly jerks and I have the shakes in my right hand," he said.
"My right side doesn't drag a bit but it is a bit slower and less strong than the other. There's a constant ache in my arm which is the way it is.
"Even though I didn't want to hear the phrase 'Parkinson's', at least I now know what it is so I can follow a path of making sure it's kept under control."
Shaun Udal was a popular figure in cricket during his career and remains so in retirement
Unsurprisingly, plenty of former team-mates, opponents and fans have offered their support following Udal's public announcement.
"It's been great," he continued. "Some people said 'why put it on Twitter?'
"But I was getting lots of calls and questions asking if it's true and I thought 'I've got nothing to hide' and it might help with the awareness.
"Michael Clarke has been in touch from Australia, people from South Africa, Kevin Pietersen, Darren Gough, some of the Hampshire boys like [Liam] Dawson.
"It's nice to get a reaction you'd hope you get but there are also some alternative people from the medicine world that have been in touch, if I need help, second opinion, drugs and stuff to make contact.
"There are good things about social media and this is one of them. It's been heart-warming to get the reaction it's got. I'm very grateful."
