Welcome to HCM,
From your signs and symptoms it seems that you are having B12 deficiency anemia
giving rise to all your physical and neurological problems.
Your B12 level is much low.
Secondly as you are 49 you might be having menopause
or pre-menopause stage.
At this age due to hormonal
changes all these symptoms do occur.
Consult your doctor and get examined and start the treatment.
You may attend menopausal clinic and learn how to overcome all these problems.
Ok and bye.
