Iodine treatment for "borderline diabetes" & jointmuscle pain

Background info:
Doctor diagnosed me with PCOS in 2011
"Cured" my PCOS with inositol,elimination of soy from my diet, & no refined sugar
Got pregnant easily in 2012, had a traumatuc birth including an emergency c-section in April 2013
My daughter would not latch so I exclusively pump breast milk for her
Currently 10 months post partum & have been experiencing severe joint & muscle pain. I had my blood drawn last week & the results show I'm "borderline diabetic". Hemoglobin A1C is 5.6 & glucose is 114. Blood Sugar level was 130.
Would like to start Iodine supplementation but would like some advice. Tweet
