At 7 years of age my mother suffered rheumatic fever which affected her heart. She is now 75, in AF with leaking mitral valve and had a pacemaker fitted 16 months ago. A life long non-smoker, tee-total for over 25 years, weighs 6 stones and keeps herself as active and as fit as she possibly can. A couple of days ago she suddenly lost feeling in both arms, they went completely numb. She felt pressure in her chest but quite high up - just above breast level. This feeling passed after a few minutes and left her incredibly hot and feeling sick. This again passed after a short while. Since this incident she has felt fine, has gained good colour and infact looks bettter than she has for a couple of weeks! She s not panicking (she never does) but should I????
