14 yr old girl with severely underactive thyroid

[Danger-Mouse]

Just started taking thyroxine (50) for 3 weeks. Legs and back are aching. Continues to be really tired. Advice please.

she will need FULL thyroid and vitamin testing 8 weeks after starting on 50mcg Levo

Likely by then ready for next increase

As per my reply in previous post here

Re your own thyroid issues

Ideally get FULL thyroid and vitamin testing via GP

Blue Horizon will test children, but possibly only at their London clinic
