About gall stones

I know I have stones. I have known since last year. I had an
abdominal ultrasound done. I seem to be having flare ups of
symptoms.So are there any hard and fast rules I should follow? What
can I change or avoid right now that is going to make a significant
noticible difference in the way I feel. I also have high blood
pressure, if that makes any difference in anyone’s suggestion about
diet or lifestyle changes I need to make right now. So, what should I
avoid, and what should I be doing?
Thanks,
Marlene
