Heeeeelp, Is a "suffocating" feeling normal when stuttering?

Heeeeelp, Is a "suffocating" feeling normal when stuttering? I do not have this condition, but i am working with kids in a shelter and there's a 7yo boy that does; yesterday while talking with him he told me he feels as if "his tongue gets stuck on his palate and he can't breathe in or out", he does get a little red as if struggling, and his head and eye twitches a bit, from what i read online, the twitching is common in people that suffer from a severe stutter but can't find anything on the "air getting stuck" situation, so i come to ask directly to people with more experience and knowledge on the subject. If it is "normal", how can i help him? Or it isn't normal and i should ask for medical advice? Any help is accepted, I am just a dietitian that's working on an intervention because malnutrition is a problem in the shelter, but i want to help him as much as i can while working with them. Thank you, all!
