John previously spoke about living like a 'hermit' and feeling 'trapped' inside, because he was heartbreakingly too embarrassed to leave his home.
In a preview clip for an upcoming episode of Dr Pimple Popper, he has a procedure done to help him breathe and reduce the size of his nose.
The TLC reality programme follows patients across America visiting dermatologist and cosmetic surgeon Dr Sandra Lee for help with their ‘spots’, whether that be a ‘third boob’ behind an armpit, or a man with 400 tumours across his body.
John had recently shared his story, beginning: 'I have a nose the size of a plum.'
He goes on to explain that over the last three decades, his nose has undergone 'big changes', growing 'twice as wide and longer'.
‘It feels kind of like snakeskin, and there’s scars, it’s rough.’
In the clip, Dr Lee carves out pieces of his nose, with the TLC caption comparing it to 'slicing deli meat'.
'Are you wincing because it really hurts' she asks him during the surgery, to which he replies: 'Not because it really hurts, I can feel it but it doesn't really hurt.'
She then instructs John to close his eyes as she cuts the edge of his nose, explaining: 'I can already see your nostril opening up.'
She later tells the camera: 'This is good because I'm taking huge chunks off of John's nose and this is really going to help him breathe better.
'I just hope that he allows me to keep going, we have some work to do, and he lets me dig deep here.'
This comes after John heartbreakingly admitted that his nose has contributed to his depression, saying he’s felt unable to leave his house.
He told a doctor: ‘Well when you sit at home, and have nothing going on, you don’t go out, all you do is sit, you get depressed.’
John continued to the camera: ‘To have this problem for 20 years is terrible. I’m trapped, I don’t get out. I don’t associate with people.
‘I’m a hermit backed up in the house.’
He tearfully added that because of his nose, he hasn’t gone to see or visit his family.
‘I don’t go to Christmas, birthdays, my little great-granddaughter, she’ll look at you and say, “Is that your nose?” It’s embarrassing.’
