difficult child has been complaining on and off of stomach pains since last Thursday which is when we increased his Topamax. Sometimes he complains of sharp pains, other time sore muscles, and still other times it is more like an upset stomach. He has vomited a couple of times over the last three days. Much of the time he seems to be perfectly fine with no pain whatsoever. At first we thought he was constipated but now it is beginning to remind me of the stomach migraines he had a couple of summers ago. The thing with that theory though is Topamax is supposed to help with stomach migraines. I guess I'm wondering if anyone knows if an increase dosage in the Topamax like this could cause such an upset stomach? I plan on calling his doctor tomorrow because this afternoon he has been really out of it. I just don't know whether to call his pediatrician or his psychiatrist.
