Speaking to Reveal, Abi said: "The filler had reacted in my mouth and it was so thick that it became a square block, like concrete, which was pushing out at either side of my lips and under my nose.
"My lip began to tear in two in the middle because of the pressure and, once that's happened, you can never get your lip back to normal.
"I was told if I left the filler any longer, it would have only got worse and my mouth would have been permanently disfigured."
Luckily for Abi she managed to rectify the damage the fillers caused, despite it taking six corrective procedures.
She continued: "While I was having the fillers sucked out my whole face blew up – I looked like a cartoon character.
"I was screaming in pain. It was excruciating."
The former TOWIE star appeared on latest episode of Katie Piper's Bodyshockers, to talk about what she went through with her fillers.
She admitted that appearing on the Essex reality show made her feel pressured into having cosmetic surgery.
"When everyone looks amazing, you can think maybe I could do this, especially as some of the girls had work done. I asked them for advice," she said.
Dr Esho of Le Beau Ideal who carried out the reversal surgery on Abi said: “Abi came to see me after a lip augmentation with dermal fillers had unfortunately gone terribly wrong.
“Dermal fillers carry real risk of cyst formation, infection, allergy and scarring and it's important to be aware of these as part of doing your research when seeking these procedures.
“Over several weeks I saw Abi in stages we worked to drain and remove deep cysts, free scar tissue and dissolve filler which had been misplaced.
“It was a painful process for her but she was been brave throughout, recovered well and is now looking better than ever.”
Abi admitted the painful reversal treatments were worth it to rid her lips of the lumpy filler once and for all.
She said: “I’m really happy, I feel so normal now but my lips will never be the same or as tight and nice as they once were.”
