Welcome to HCM. I have gone through your question and understand your concerns.
Your over active thyroid can have recurrence. It can happen years after cure of hyperthyroidism
Please share with us your current medications and recent lab reports. Thyroid medications are not started on symptoms but based on thyroid function tests
. This is because most thyroid disorders are without symptoms and these symptoms are not specific for under or over functioning thyroid.
Hope I have answered your query. If you have any further questions I will be happy to help
With warm regards,
Dr Ajish TP (MD,DM)
