Thyroid level fluctuates. Sometimes its 8.36 and 5.5 and somtimes normal. I feel diziness when walk on road and feel exhuasted in very little work. Seems to take rest everytime. Feel chest pain on left side and sometimes on right side. I am feeling it from last 8 months. Consulted so many doctors but no one is able to catch the problem. Now I think it may be due to thyroid. Pleawe suggest me what to do.
