Has anyone out there had RAI as treatment for graves and it didn’t work … my poor son had it 9 weeks ago and at 7 weeks was very overactive and just had another blood test on Monday and it’s even more overactive … they are putting him back on carbimazole. I’m still praying for a miracle and hoping it might still kick in and do what it was supposed to do and just wondered if anyone out there has experienced this and can give us some hope that it might still work? Thank you
