Thanks for your query. I appreciate your concern but would like to have a complete workup of your mother before jumping to any conclusion. You mention that she gets, headache, dizziness
, tired feeling, "restless legs", high blood pressure
and falls down. You also mention that she has "low iron" and it taking B12 shots. What about her mediciines for high blood pressure?
In my opinion you need to consult a discuss with your physician who may involve a neurologist
and/or a cardiologist to do a complete work-up. She may be suffering from transient ischaemic attacks which can be diagnosed by relevant investigations like doppler study of the carotid arteries. However I will not jump to any conclusion till a complete work-up has been organized.
Wishing your mother all the best.
