Hi there , some of your symptomatology suggestive of thyrotoxicosis
. Commonly occurs due Increased hormones( thyroid hormones) production from thyroid gland( also called as Hyperthyroidism
) . This disease is quite common among young females. Weight loss
, loss of sleep , palpitations , neck swelling , menstrual disturbances etc are the other problems patient faces due to this disease.
I suggest you to visit a Physician for clinical examination and doctor will order Thyroid profile test to confirm the diagnosis.
