Your mother is perhaps suffering from osteoporosis
, a condition of thinning of the bone material causing pain in the bones. This usually occurs after the menopause
but in her case it might have started early owing to the hysterectomy
. She might also be suffering from problems in her spine causing the pressure symptoms like tingling and pain. Pain in joints is usually due to arthritis
and since she is overweight
, it is common for joints to take the extra strain. She needs a complete orthopedic assessment and so, I advice you to take her to an orthopedic for treatment. Take care.
