I am possible here a little early, my son is nearly 16, diagnosed with a brain tumour as a toddler, the last 3+ years he has been fatigued. But he has not had any treatment for over 4 years. I think we figure out what's wrong and we get a few good days then he's back to sleeping. What doesn't help is that he has so many doctors and each one looks at their speciality and says that bit is fine, but some thing is definitely not right. Will things be easier to sort out when he is in adult services?
