My16 year old daughter has been running fever for 9 weeks, she also has extreme fatigue, headaches, night sweats, and muscle weakness (difficulty going down the stairs). She has been tested for mono (cytomegalovirus antibody, & Epstein barr) TB( QuatinFeron Gold) Toxoplasmosis Antibody, Rickettsial Antibody, Valley fever ( CF Titer and Coccidiodes Antibody) and chest X-ray - all negative as her illness started with respiratory issues.
She then started having cardiac issues. Orthostatic intolerance, hypertensive, and tachicardic. Her EKG and cardio echogram all came back fine, and in the last three weeks her blood pressure and heart rate have normalized.
She was had multiple blood cultures, CBC's, and CBC with differential, C-Reative protein, Immunoglobulin A, M, and G, Lactate Dehydrogenase, sed rate, Tcell subsets extended, HIV, and uric acid lab work.
All testing has come back normal.
She has seen a cardiologist and a infectious disease specialist who have been unable to find out what is wrong and are suggesting we wait and see if it doesn't self resolve. She currently sleeps 16+ hrs a day, and has no appetite, and can't go up and down the stairs by her self. She can't stand or walk any distance with out getting dizzy, and frequently has headaches. She has been pulled out of school also.
Does anyone have any suggested course of testing or recommendations?
