Hi, many thanks for the query!
Yes, these are the symptoms of Hyperthyroidism
, but to come to an exact diagnosis, you need to do your Thyroid profile including- T3, T4, TSH
Dont worry, if its hyperthyroidism, it is completely curable with medicines.
For body knots you should get physically examined by your doctor so that if these are enlarged lymph
nodes, one can search for foci of infections, that can be treated with appropriate antibiotics and if these are not the enlarged L.N.,
FNAC (fine needle aspiration cytology) of the swellings should be done to know their histopathology.
Wish you a good health. Take care.
