My Grandaughter, Megan, 9 yrs old, had a urinary tract infection last week, at the time she had a high temperature. A course of antibiotics appeared to make her Semi well again. However, today, 9 days on from that episode, she has a very high temperature, no obvious symptoms of urinary tract problems, as she had previously, total loss of appetite and is generally unwell, she has complained of constant dull abdominal pain.
