imo I would go see a dr that deals only with this and get checked.
You may have to go to the nearest city or farther, I was lucky with my son there was a specailist in the largest city close to us. He has PDD
Here is a article i found.
Also as with anything in life i think syptoms are always more out there when stressed
good luck to you I hope this helps
