Hi..
have u ever experience thyroid problems before?
sometimes, although the test came back fine, u might never know that u r having thyroids cause although it's normal, u still can have thyroids like all those symptoms that u describe. i don't know whether it's a hyper or hypo or maybe hashimoto- usually in between hypo and hyper where u nearly have both the symptoms.

from what i know through my friend who experience thyroid problems before, he said that

Hyperthyroid:

Common hyperthoyoid signs and symptoms in adults include insomnia, a higher pulse rate,hand tremors, exciteability or nervousness, feeling unusually hot or cold, excessive sweating, joint pains, puffiness around the eyes and the appearance that the eyes are becoming enlarged.

Typical symptoms among the elderly include muscle weakness, especially in the shoulders and thighs. Patients with heart problems may experience increased chest pain and shortness of breath.

while Hypothyroid
Common symptoms among adults include decreased appetite, increased weight, dry skin, hair loss, a deepening or unusually hoarse voice, puffiness around the eyes, Depression and loss of intellectual abilities.

currently this friend of mine is taking doctor prescription medication but at the same time he's also taking Heatlhguard T18 from singapore. it's TCM Tablets, natural herbs. he says that it seems to help him get under control of himself and cause great improvements to him.

i don't know much, maybe you could give a try or something.?
