I have been suffering from hand tremors and muscle weakness, which affect my ability to perform daily tasks. My hands shake a lot, causing me embarrassment, and this has been happening since I was around 14 to 15 years old. A doctor advised hormonal tests, and my report shows the following: S.Free T4 is 1.09 ng per dl (Reference range 0.8 to 2.0) S.TSH (Ultrasensitive) is 2.4 uIU per ml (Reference range 0.4 to 4.5) Active Vitamin B12 (HoloTc) is 36 pmol per L (Reference range 30 to 165) Are these test results normal? Is my report normal? Also, what could be the actual cause of my hand tremors and muscle weakness?

Symptoms may be due to borderline B12 or essential tremor. A neurologist consultation is advised for tremor. Consider B12 supplementation.

Hi, my blood report says predominantly normocytic normochromic with macrocytes and ovalocytes. What does it mean and what could be the cause? What is its effect and how can it be rectified?
