Her 7-year-old son, Triston Galvan, was seriously injured in a car wreck in south Abilene six months ago.
Since then he has had several surgeries, but hasn't seen dramatic improvements.
Duncan says, "Since about Christmas, he's just been in more pain and it's hard because you don't know whats wrong with him. He can't tell you, so you kind of have to guess."
As any mother could imagine, it has been difficult for Duncan to see her son go through this.
"He used to have movement in his legs. Now you can't hardly bend them. He's just not comfortable. It's hard on us and I know it's really hard on him," she says.
Soon he will receive a Baclofen pump to relieve some of that pain and help with his muscle-toning.
"His neurologist thinks once we get his muscle control and everything adjusted then we can really focus on his cognitive," says Duncan.
Before that, he will have to have a prosthetic piece of skull placed in his head.
"The bone flap that they had put back on, the piece of skull that they had put back on, was his but his body's not accepting it and so it's starting to reabsorb itself," says Duncan.
After nine surgeries, Triston is still in his bed recovering, but his mom remains hopeful that one day things will get better.
She says, "That we're able to communicate better than what we are now because it's really hard now to try and understand what he's going through."
