I take 72mg of concerta as an adult and don't have this problem, but I do remember reading somewhere that some people can get this feeling.
When I was researching this drug on the internet I came across it somewhere. Try doing a search for Concerta on the internet? I have noticed lately that I am getting some muscle twitching in my arms and legs and shoulder, and once in my butt muscle. I never had this problem before and will monitor it. Do you think she is having muscle twitches? They are annoying, but don't hurt!!
Let us know how it goes - there are some people that are on this medication and it would be informative to find out what the Doc thinks!
The Dr. said to go without the Ritalin in the afternoon..And she says it is not bad today as it was yesterday..And she had been drinking some caffeine and no caffine this afternoon.
