Hi,thans for your question.
You are Hypothyroid from last 10 years and are on cardrone 100 mg from last 10 years.
You are having Hypertrophic cardiomyopathy
This,could be due to hypothyroidism
This,time your TSH
levels are high despite on medicine.
This indicates your dose of cardrone is less and you may need increase in the dose.
IUCD insertion does not bothers me.
However,your leg injury
has got infected (as leg has swollen)and may need a course of antibiotic for infection .
I would suggest you to consult a physician who will evaualvate you for increase in the dose requirment of cardrone as well as examine your leg injury
Hope this answers your question.
