hi. my son is 13 years old and in the last two weeks we have noticed him blinking constantly,and not just a normal blink its very forceful and 4 to 6 at a time with his entire forhead scrunching when he does it.over the last few days it has got much worst and alot more frequently. I am very concerned,along with he had corid plexus sist on his brain before being born but they had rupchured with no problems. please info on anything that could be causing this or maybe could be a underlying problem . thank youView Thread
