started using ice on knees twice a day and noticed blood pressure lower although I reduced my blood pressure medicine in half it is  so low that my home machine could not detect reading. found a wrist one and got 89/60 when I dont remember being so low. Could ice be the reason?
Thanks for your question on Chat Doctor. I can understand your concern. No ice pack application on knees, can not cause blood pressure reduction. So no connection between ice application and low blood pressure. In my opinion, your blood pressure is very strictly controlled with Chat Doctor.  So you should consult your doctor and discuss lowering the dose or medicines to achieve normal blood pressure.Don't think ice application is the cause. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
