Thought disorder symptoms and conditions

I am simply astonished by what I am reading my 8yr old son has been taking singulair off and on for about a year he too would complain about his legs hurting to the point where I would be in tears just watching him. Most recently we started him on meds for add/adhd i noticed the days when he would not take the singulair he would do wonderful in school,however when he took the singulair he would have low attention span, disruptiveness,etc. now after reading this post I'm wondering if he really has add or if it was the singulair. --Thanks lgbeaumont

I can't believe what I'm reading tonight on this page, I decided that today was the day I needed to check up on side effects of singulair, since my 5yro, needs his 3rd refill. Three weeks ago I took my boy to the doctor, because of severe weeknes,fatigue. irritability,lose of interest in studying, in sports, in home works, and lose of appetite one of my main concern, I ask his ped if maybe these could be side effects from his singulair, She said no way she hasn't heard of such effects from this drug, and that the side effects form singulair was realy mild, I took her word on it and continue my poor lillte boy in the hell he is living in, oh. she send him to the lab and draw blod for a series of exams, but find nothing so I continue my days wondering and suffering for my child, My mother-in-law even recomended counseling for my boy since we have a new baby at home, tonight I decided before getting his reffill why not do some research and find out what other people are saying? this is the first page i ran in to and I know that I dont need to read much more to take my boy off of this singulair.
ps. we can not rely on our doctors to talk bad of any drug.
