I was ill with shingles about a month before getting metal braces. 48 hours after having them fitted I went into a fog, glands up, pins and needles anxiety insomnia (usual stuff) and stayed that way until 22 months later. At the 21 month point I'd had my braces removed due to suspecting it may have contributed towards my immune system falling to pieces. I did get a diagnosis of glandular fever though from blood results. Im at about 90% physically thankfully. Has anyone else experienced braces and CFS?!
