Jamie Doyle (18) has undergone two brain surgeries since he collapsed in Lanzarote where he had had been saying with his mum Mary (50), dad Stephen (52) and a friend.
Jamie, a barber and talented boxer from Banbridge, Co Down, had woken up with a severe headache before his friend George rang an ambulance.
He was airlifted by medical teams in a Lanzarote hospital to Gran Canaria after they realised the severity of his condition.
He has since had two brain surgeries at the hospital, including one to remove a clot in his brain, while the second was an emergency operation to remove part of his skull in a bid to reduce swelling.
Jamie will be kept in an induced coma for the next four to six weeks in a bid to try and reduce the swelling on his brain.
He will then have to have more surgery to reattach the piece of his skull that was removed.
According to his fundraising appeal on GoFundMe, Jamie’s mum and dad are by his side but help is needed for the mounting surgery costs.
“Jamie has gone through 2 surgeries on his brain so far within the last 48 hours,” the GoFundMe appeal reads.
“Early on this week his family suffered a devastating loss of their newborn grandchild.
“Obviously they cannot be at home to support their other son Dominic through this devastating time.
“What this family are going through is unimaginable so please if you can help in raising some well needed funds to cover the cost of their beloved sons medical bills and their accommodation in the coming months it will be so much appreciated by Jamie’s family. We are all praying for Jamie and hope he pulls through.”
So far, £56,270 of a £100,000 goal had been raised and people have been donating while leaving messages of support.
“Heartbreaking, I don't know your family but my thoughts and prayers are with you at this awful time and I pray that your son makes a full and fast recovery," one person has written.
Another adds: “Wishing all the very best to Jamie and the whole family. My thoughts are with you all.”
