Again 100 mg epivir-hbv with amex, his parents took him to the pediatrician, but the doctor could find nothing wrong. He referred Justin to both a urologist and a neurolo- gist at the local children’s hospital. Neither of these specialists could deter- mine the cause of Justin’s problems, although after numerous tests, the neurologist did find that he was indeed suffering from impaired short- and long-term memory, which accounted for his forgetfulness. She also docu- mented evidence of numbness and decreased sensory perception. Now Justin’s parents were worried sick and begged the neurologist to do something. She put Justin on a regimen of multivitamins and screened him for diabetes and thyroid problems. Not only did the boy’s symptoms not improve, but he was also in a foul mood all the time and becoming less and less motivated to do anything. He wouldn’t even attend Boy Scout meet- ings, the one thing he’d always loved. Fortunately for Justin, his mother and David’s mother, Hilary, shared a carpool. Noting Justin’s frequent absences, Hilary inquired about his health and his mother confided in her. Hilary told Justin’s mother about how she’d solved David’s mystery malady using the Eight Steps. She bought a notebook, listed Justin’s symptoms in detail, and com- pleted all the steps until she reached Step Five (past and present mental or physical problems). At that point, she decided to sit her son down and dis- cuss it with him directly.

These days were random generic 100mg epivir-hbv visa, but Jessica’s mom, Marsha, knew just how sick her daughter was when it also happened on music-class mornings. On those days, Jessica would sometimes remain in bed until midday when she finally felt well enough to get up. There was just one problem: by the time she arrived at the doctor’s office, Jessica appeared normal. Jessica must have visited her pediatrician six times over a two-month period, and each time her doctor could find no physical evidence of a prob- lem. Finally, he suggested a referral for what he called “attention-seeking behavior. Nevertheless, she followed the doctor’s suggestion and took her daughter to a mental health counselor “just in case. The other possible diagnosis he suggested was a “school phobia,” where a child complains of pains on the morning of or night before school and con- sequently has a poor attendance record. In these cases, the pains usually resolve after the school bus has left. He reported that he didn’t know the underlying reasons for this yet, which would require further sessions to determine. Marsha thought all of this was utter nonsense since her daugh- ter loved school and wouldn’t miss her flute classes unless she truly felt sick. So Marsha took Jessica to a new pediatrician who couldn’t find any- thing on physical examination either and suggested that perhaps the girl had growing pains—recurrent limb pains that occur during a growth spurt. When he explained these growing pains usually occurred at night, Jessica herself spoke up and told the doctor her pains were worse in the morning. The doctor commented that this would suggest an arthritic condition, but Does Your Child Have a Mystery Malady? He repeated her blood tests and they were consistent with the earlier findings. She began having spiking temperatures and joint swelling, different from the stiffness that was described earlier.
