Welcome to HealthcareMagic. Since you are a 50 year old female, this feeling of burning and pain in hands and other joints can be due to menopause induced or due to arthritis
. Symptoms of menopause are irritability and mood swings, hot flashes, night sweating, irregular periods
, decreased blood loss during periods, dry vagina, breast heaviness and tenderness and joint and muscle pain
I suggest you to consult a doctor and get prescribed hormone replacement therapy
. To rule out arthritis, you need x-ray and MRI of the joints and RA factor done by blood tests.
Hope it helps you. Regards.
