Perched on a sofa in his family's home in East Jerusalem, Reda Obeid is wearing fresh clothes for the first time in months.
But along with his black track suit and shoes, Reda is wearing disposable latex gloves.
They are a bright blue reminder of the ordeal he has just experienced.
"You scratch so much that you draw blood," Reda said.
The 18-year-old's thin frame is covered in scabs and sores.
When the ABC met him he had just been discharged from hospital, where he had been treated for scabies.
Reda said he picked up the skin disease while he languished in a crammed cell at the Megiddo prison in northern Israel.
"We stayed in the same shirt and trousers from October 7 until November 20," he said.
"I got the disease from lack of hygiene — no clothes, no washing machine, no dryer, we had no washing powder."
Reda alleged Israeli authorities refused to treat him and others suffering from the ailment, as it ripped through the prison.
It was only when he was released on Thursday, one of 110 Palestinian prisoners and detainees freed in exchange for Israeli hostages handed over by Hamas in Gaza, that he could seek medical help.
His family arranged for an ambulance to rush him to Jerusalem's Makassed Hospital.
The joy of leaving prison has been tempered by his illness, which has left him wearing gloves to avoid passing the scabies to his family and friends, and unable to hug his loved ones.
"People would not believe what we are going through inside jail," he said.
"There are things I am not allowed to talk about."
Celebrations curtailed in East Jerusalem
On Thursday, there were chaotic scenes as hostages and prisoners were freed.
In southern Gaza, a crush of people surrounded two Israelis and five Thai nationals as they were handed over by Hamas and Palestinian Islamic Jihad to the International Red Cross.
In the north, another Israeli was released, and celebrations erupted in Israel as the groups were driven across the border.
Hours later, there was jubilation on the streets of Ramallah as dozens of Palestinians were driven by bus from a jail in the West Bank and set free.
But in East Jerusalem, where Reda Obeid and his family live, it was a very different story.
The area, annexed by Israel decades ago, comes under direct control of Israeli authorities.
As prisoners such as Reda were delivered to their families, they were warned there would be consequences if they were seen to be revelling in the moment.
Israeli police and intelligence officers arrived at the family home in Isawiya, checking only immediate family were on hand to greet Reda and ensuring a party was not being planned.
A drone hovered overhead, monitoring movements in the street outside, as officers patrolled the street.
Beatings and intimidation in jail and at home
Reda suggested the behaviour of Israeli authorities after his release was an echo of his treatment behind bars.
He was arrested last August, charged with throwing stones at police in East Jerusalem, and kept in a police cell.
"They handcuff you, humiliate you, swear at you, they force you to bark like a dog whenever they want it," he said.
In October, he was transferred to the Megiddo jail.
"They take off your clothes, and when you are naked five guards entered the room," he said.
"They enter and start to beat us — that's the welcome ceremony.
"They beat me with a belt while they punched the other detainee — I remained silent, because when you talk they beat you."
For the last week before his release, he was not allowed to shower.
In a statement to the ABC, the Israel Prison Service insisted "all prisoners are detained according to the law."
It said it had no details of alleged mistreatment in jails, detailed by Reda and others recently freed from other facilities across Israel.
"All basic rights required are fully applied by professionally trained prison guards," a spokesperson said.
"We are not aware of the claims you described and as far as we know, no such events have occurred under IPS responsibility.
"Nonetheless, prisoners and detainees have the right to file a complaint that will be fully examined and addressed by official authorities."
Fear of speaking out
Speaking so soon after being released, Reda and his father Mohammad both agreed there is a risk in going public.
It is a particular concern given Reda's brother Dia, 19, is currently held in another jail.
His family have not heard anything about his wellbeing since he was arrested a couple of weeks before Reda was detained.
"After I saw [Reda] in the state he was, I cannot imagine how my other son will come out," Mohammad said.
