My son, age 6, has always been a finicky eater and until recently, on the verge of underweight. He's almost always had dark circles under his eyes. He has been diagnosed with allergies and asthma, both of which are being managed. But he is also always very pale, which is not something I would consider hereditary. His father is Polish, therefore fairly dark complected. I have a lot of Cherokee ancestery myself and am not exactly fair skinned. He's been 'sickly' since entering the world, seeming to have a low immune system, but the doctors brush me off and say he's fine. NOW, since February of this year, he has had two seizures. He has an appointment with a Neurologist, but not until July of this year. The symptoms may all be totally unrelated, but he just doesn't seem like a normal, healthy 6 year old little boy. Anything in particular I should be looking for or checking up on as far as diseases, syndroms, infections, or just any specific conditions I haven't mentioned we've already addressed that sound like they could be of concern?
