I had RAI in Feb 2010 for Graves' and was having all sorts of issues, including swelling while on T4 only meds. After adding synthetic T3meds I saw much improvement, but was still having hypo symptoms. Just made the switch to armour 8 weeks ago and am feeling much better. It will take your body time to adjust. What dose of T4 meds were you on? How much Armour did they start you on? Please post your labs if you have them.
Do you have recent thyroid labs to post? If so, please do with reference ranges (they have to come from your own lab report since they vary lab to lab).
The symptoms you list are usually symptoms of hypo (undermedication) rather than a reaction to the medication itself. You've tried Tirosint, which is hypoallergenic, so I doubt it's the fillers or binders in the pills that are bothering you. It's much more likely that your doctor has simply not found the correct dose for you.
Also, when was you RAI? It can take up to a year for the thyroid to die off completely, During that time, as thyroid tissue dies, it "dumps" hormones into your blood making things a bit unstable for a while.
Were almost the same situation.. hyperthyroid after RAI now im hypothyroidism.
base on my experience, the 1st time i take medication for hypothyroid. i take synthroid 100mcg after 2weeks increased to 125mcg, another 3weeks increased to 150mcg. then stick to 150mcg for more than 2yrs. after that i shift to thyrax 150mcg. while taking my medication i feel some symptoms i dont think if its a side effect/allergy or a symptoms of hypothyroid, i just continue taking my medication. @ while taking a new brand of medication. i got some strange symptoms.. it takes 4 to 5 weeks before i recovered and back to normal.
some times got blurry/vision. muscle weakness. etc. or unexpected strange symptoms.
@ my condition sometimes goes up & down.
better ask your dr. what you feel.
Just continue taking your medication.
