hi my 17 year old son has a fear of needles and i am at my wits end.it all started a while back when he came with me when i was having a blood test and he fainted.the next occasion was when he was having a mri scan he had to have some liquid injected to show up on the mri and again he fainted.then on another occasion he had to have blood tests and he fainted and then had a fit.well today we went to the hospital and they wanted to do blood tests to rule out arthritist and he went mad ,all his body tensed up and his skin went bright red and he got so angry and he told the doctor no way and walked out.it took me about an hour to calm him down but i am finding it hard to talk to him,all he has said is there is no way he is having a huge needle pushed up his veins.i would really appreciate it if any one can give me some advice on what help i can get him.thanks
