I have a 14 year old daughter who has had a headache for 5 months. Nothing over the counter helps. She is tired, not thinking very clearly, often complains of sore throat and stomach ache. MRI came our clear. Labs are good but eosinophils came out at 5 and monocytes at .6 . Also the alk phos isoenzyme liver fraction at 11 and bone fraction at 89. Could she have parasites that are causing the headache? What can we do?
