Thanks for thr query,
You need evaluation by an endocrinologist
and physician . Thyroid
problems, abnormal blood sugar and at times hypothalamic dysfunction
can account for all the complaints that you have. Your physician will determine the need of a brain scan to rule out any caue that can cause headache along with similar comaplaints. The management will depend upon the cause/diagnosis.
Stay relaxed and get evaluated.
Hope this helps
