Crumbs this is infuriating- your onc knows higher cholesterol is a side effect so guess he just wants to treat you for breast cancer so handballs you to the gp for cholesterol lowering medication still bloody not good enough with all the other pieces to the the puzzle not within gp’s grasp.Think it means he doesn’t want you off hormone therapy and wants someone else to manage side effects.I know dr google is not ideal but we may need to be more proactive with our healthcare and use credible medical online resources to help ourselves.I started reading about the DASH diet from the Mayo clinic which is supposed to lower blood pressure.Maybe there a little dietary mofications as well as exercise that might help.eg I know rolled oats lowers cholesterol and blood pressure.Its simplistic I know but little things may help as an adjunct to medication. My blood pressure’s rising just with the lack of help you have received. One thing I did read re hypertension is that you are on the right track with magnesium plus they recommend Calcium and Potassium too.Oh Mel I don’t know how to help you
