Professor Green battles rare disorder, undergoes surgery.

Professor Green has revealed he is battling a benign tumour behind his eye and three on his spine while sharing insight into his 'painful' and rare health condition. 

The singer, 42, real name Stephen Manderson, listed his ailments which include , Autism, Pyloric Stenosis [a narrowing of the opening between stomach and intestine] and Factor IX deficiency [a blood clotting disorder].

He went on say that he'd also recently been diagnosed with Schwannomatosis, which is a rare condition that results in multiple benign tumours and can cause debilitating pain and neurological dysfunction.

Taking to Instagram on Sunday the chart topper said that he'd had 'superficial  but painful' growths removed from his head and neck, before doctors discovered similar elsewhere on his body.     

He posted a snap of himself looking frustrated with the caption: 'If only genes came on hangers and you could choose your perfect fit'.

The singer went on to pen:  The combo of my parents handed me ADHD, Autism, Pyloric Stenosis, Factor Vii deficiency and the latest addition: Schwannomatosis.

'My nerve sheath tumours are thankfully benign, but chronic and not without complications - some more than others depending on their location'.

'After four relatively superficial but painful growths were removed from my head and neck, i’ve now found out i have one behind my left eye and three along my spine: two smaller lesions at t5 and t6, and one the size of a blemmin’ lime around my s2 nerve'.

He went on: 'After a good few weeks of worrying about whether or not they were benign or malignant, I feel as though as painful as this is (I thought it was ‘just’ worsening sciatica), the trauma I went through in my head living out worst case scenario’s was worse'.

'I’ve come to a place of acceptance - this is how i’ll experience life, there’s no way around it, and that’s okay. what isn’t okay is descending into cyclical thought, nor is catastrophising or dreaming of some other reality - both are avoidance and neither conducive to being present'.

He continued: 'Its hard knowing whats owing to what sometimes - is the physical pain causing mental anguish, or is my mental load manifesting physically? again, its probably not worth too much thought - i’m doing my utmost to acknowledge, accept and exist wholly and fully without becoming avoidant and being somewhat willingly distracted by it all. though hands up to having been hijacked by it all for a few weeks'.

'I likely suffer hyper-interoception; an overactive ability to feel internal sensations, which i’ve only found out about post autism diagnosis. it’s helped me make sense of a lot… and allowed me to pull my focus away from it when i realise i’m becoming obsessive'.

Before adding: but first i have to realise…its an intense experience, but its mine, and its the only one i’ll ever know. Working towards ‘not everything is okay, but i am’ and doing better some days than i am others but working with whatever i have on any given day'.

Before ending the post with: 'To anyone suffering with anything chronic - I see, hear and feel you! back to programming as usual'.

It comes after Professor Green shared an insight into the exchange he had with his ex-wife after they made amends following their bitter split.

The rapper and the former star, 36, are now on good terms and reconnected when she released her book 'Bad Drunk', about turning to sobriety.

The former couple also had also been told they have following their break-up and bonded over the fact they received later in life diagnoses.

Sharing details of their exchange, he told the Sun: 'We [me and Millie] spoke when she was releasing a book about her being sober and we spoke around that because I was mentioned in the book and she just wanted me to know that it was coming out and it was a really respectful thing to do.

'It was very cordial, it was over email. We laughed a little bit going "you're ADHD… me too".'

The former couple ended their three-year marriage in 2016, and Pro Green confirmed last year that they were back on speaking terms after nine years of silence.
