I’m posting on behalf of my dad. He was diagnosed with papillary thyroid cancer in Sept 2016. He had a 6 and half hour operation to remove his thyroid, 2 parathyroids, and over 40 lymph nodes as it had spread. He then had one dose of radioactive iodine and in early 2017 was given the all clear.
After the op, he was initially put on T3 but leading up to the radioactive iodine, it was swapped to T4, which he stayed on since.
In the last year or so, he has had progressive muscle weakness, primarily in his legs. Also muscle twitching and cramps, which then spread to his arms. The dr referred him to a neurologist who initially said his nerves were fine. More recently, he had an EMG test to check his nerves and was then told they were 98% sure he has motor neurone disease.
In the last few weeks, his oncologist put him on T3 (as well as T4) as he told him that 20-30% of people can’t convert the T4 in their bodies. My dad has had some slight improvement on T3, the cramping has stopped and the twitching has decreased significantly.
Can anyone shed any light on this or has had a similar issue? We are praying that it’s not MND as they’ve said he has 4 years max left if it is.
Thank you.
