Thanks for asking question on HCM!
I really appreciate your concern for your mom.
Amlodipine is an effective drug used to reduce the
high blood pressure with minimal side effects.
The most commonly occurring side effects include:
Swelling around the ankles (oedema),
constipation,
palpitation (due to increased pulse rate), feeling of warmth, redness of the face, neck, arms.
The other side effects which are uncommonly occur are
burning, crawling, itching,
numbness, prickling sensations.
It seems your mom is having these uncommonly occurring side effects.
I advise her to consult her doctor for proper evaluation and possibility of using alternative medicine to reduce her high BP.
Wishing your mother a smooth and speedy recovery.
Best regards!
