Welcome to HCM,
You are recently detected to have Hyperthyroidism
with two nodule in thyroid.
If Thyroid hormone is secreted in excess symptoms can be controlled by giving Beta blocker
it is better to give non cardio selective one like Propranolol.
We need to do FNAC to know nature of nodule to differentiate between benign and malignant one.
The other way is to do radionuclide
scan to know hot spot or cold spot.
You can be given anti thyroid drugs and other alternate are surgery and radioactive Iodine
Suitable therapy is selected according to requirement of patient.
Please take care
