Hyperthyroidism

My mother age 60 went to her GP with extremely high BP 220/90 and fast heart rate of 120. As well as adema in her ankles. The GP did numerous tests and gave her meds to combat her BP and heart rate and came to find out that her thyroid levels were very high. Her TSH was 0.05. Her T3 or T4 levels were at 14.3 or something on those lines. He had her get checked for an ultrasound of the thyroid, which showed a nodule. He then put her on Methimazole. Over the course of 3 days after this, she had only been getting worse, not getting out of bed, sweating, shaking, severe muscles weakness, dehydrated, high and low blood pressure alternating and extremely high heart rate. They admitted her to the hospital where they did more blood work. She stayed there for a day or two and they discharged her again by saying take the Methimazole. What I want to know is what is causing the hyperthyroidism. Is Radioactive Iodine a better alternative. What are some questions that I should be asking the Specialist that we will be making an appointment with, since we NEED answers. She is still very sick and not improving at all. Thanks

I'm currently dealing with a hot nodule.  So far, I have learned this is not a fast process.  5 different Dr.s referred me to an endo.  It takes a long time to get an appt.
I'm scheduled for RAI on 12/10.  Meanwhile Atenolol for BP and methimizole are helping a lot.  I have learned to just take it easy.  Too much activity makes me run a low grade fever (<101).  This will knock me flat for 2-3 days.
I think it took about 30 days on methimazole for my hands to stop shaking.
Her Dr. might order an RAI scan.  For me this took 2 weeks to get on the schedule and another 2 weeks to get the results.  This scan can help determine if it is thyroiditis (which is temporary), Graves (which is autoimmune), or a hot nodule(which probably won't go away by itself).
You might ask for some anti-body blood tests also.
This hyperT stuff is very complicated.
Meanwhile, let her rest!  You can do the shopping, laundry, vaccuuming, etc. for her.
