My 14 year old daughter has been off and sick for 2 years following an episode of mono. She's had dizziness, nauseaus, feeling EXTREMELY hot, lots of weight gain (from 67lbs in Aug 07 to 103) , missed periods last 6 months, unusual acne/oiliness for her, off and on leg pain, swolen neck-puffy face, and extreme exhaustion. She had the dizziness, nausuea, and feeling hot off and on the past 2 years and recently after she was ill in Feb. everything esclated and she has been worse. We've had lots of test and her thyroid anitbodies (TPO-TG) were elevated, her testosterone was elevated, her growth hormone was slightly high, prolactin was within limits but on upper end, LH and FSH were low, cortisol (10 both morning and noon) and progesterone was low. After she wasnt better they did an ultrasond and she had noduels consistent with Hashimotos-they put her on synthroid. It helped some with the exhaustion but she is still very sick. One odd thing I noticed was when she gets really hot and i feel her it is often just her upper arms and head/neck area. She also gets very puffy in the face as the day goes on-it seems moving around makes everything worse. Her dr said to give her Vit D in large doses but that also makes her worse. They did a Brain (not pituitary) MRI and it was ok. They also did an ultrasound of her abdomen. Any Ideas?? I am so worreid and exhausted of not having an answer. We have had to take her out of school because she feels so bad and just need to help her.
