I understand your apprehensions. The worst part is waiting to see the specialist. Your son may need further testing. Then based on the test results he may need specialized programs to help him cope with the medical problem he has. All the best! Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
Yes it all depends on his unique issues. My son took 3 visits when he was 11/12 years old. We got the diagnosis confirmed three days later. It was a few different people from differing specialties who cooperated in my sons case.
Once the diagnosis is confirmed you should ask the specialist what therapies may be needed and the steps you need to take to get documentation signed for approval. That depends on your health insurance coverage.
The sooner therapies are started, the better. You will have to do quite a bit of adjustment.
