Definitely get the thyroid tests {{{{{bowzzie}}}}}
the first symptoms we got when our thyroid went down were what they now choose to call "fibromyalgia-like" symptoms, also GI changes can be a common symptom
vitamin & mineral testing would be good too, in fact make them do every test you can think of (we might be able to help with the list)
will you get this free ?
we have to supplement what the NHS pays for some tests

& dentists cost a fortune
when do you go home ?
