I know you're confused. It's hard going through all of this with a child, S.. You feel like you are walking through molasses with the varied opinions from different professionals.
No one here can give you a real answer to your question about the swirls. I guess you could research it, but honestly, I'd just leave that alone. Instead, what you need to do is get as many services for your son as you can. Speech/language, occupational therapy, and a special needs preschool. You could ask for a play therapist to come and evaluate your child. A good play therapist really does understand a lot. They spend a lot more time with your child than in a doctor's office, and they make recommendations to the doctors.
Is there a children's hospital near you? If there is, you might get an appointment with their developmental pediatrician. You would want to take all the reports you have from the doctors with you to this appointment and ask him/her to put together a team of professionals to help you. A children's hospital also has a social worker to help you.
Whatever is the problem with your son, the most important thing is EARLY INTERVENTION. You get him the services he needs to help him. Even without a definitive diagnosis, you work the problem. Make it your mission to get him the help. I promise you that it will make a huge difference in his little life.

Okay - swirl. Is it kind of like a cowlick? You're talking about his hair? If you are, some people do have those. Sometimes they are on the crown, and sometimes also above the temples. You have to end up having a hairdresser who knows how to work around the cowlicks.
If you're not talking about hair, then I don't know what to say.

I looked up the word "sworl" in the dictionary and cannot find it. I don't know what you are asking here, so I can't help you.
