I am not sure if these are thyroid symptoms, but I have them also.
I was diagnosed with Graves in March 08, had RAI April 08.
I developed tinnitus (ringing ears) around Jan 08. I have read of afew instances of this symptom being related to Graves, but my Dr. says no.
The muscle fatigue is thyroid related.
Although my levels are all within range, I still have these problems. I am trying to get my Dr. to increase my meds, but he doesn't agree.
It takes awhile to get your levels straight after TT.
