Is my son Autistic

I realize that no one on here is able to make a medical diagnosis.  I am just a mom looking for advice from other parents.  Here is my story:

My son is now 6 almost 7.  Developmental milestones were normal other than speech.  He did not fully communicate until after 3.  He has always walked on his toes and we are unable to break this.  When he walks he is either spinning or flapping his arms.  Sometimes he touches his middle fingers to his thumb very rapidly.  All symptoms of autism, that much I know.  He adjusts very well in social settings and communcates with his peers very well.  He does mostly prefer to play alone or with only one friend.  When he was younger he used to line up his toy cars or turn them over and spin the wheels.  His teachers in the past have stated that something is wrong.  He does not stay on task and does not complete his work.  He is also usually in his own world.  Also any loud noises seem to disturb him and he will cover his ears.  My biggest question is can this be autism?  Everything that I have read states that autism is a social disorder.  Socially he is for the most ok.  He will talk to anyone and everyone.  His dad's cousin in autistic and his aunt has stated to me that I need to have him checked out.  She also told me that the school can test him.  Is this true.  We live in Texas.  

Thank you so much for your time in reading and responding to this post.

Sincerely,

A concerned mother

I feel every parents pain when I read therir story, because I have been there and nobody offers help sad to say. First get well informed go to Autismone.org and there are plenty of other sites too. Dont be scared to hear your son has Autism because there is hope and help. Find a good DAN Doctor. The Doctors never give any information other then the diagnosis. There is so much breakthroughs now in treating Autism, some children even get fully recoverd so please be well informed and about your options.
