I have corrected my typing error I am not on 400mg it should have read 40mg. Thanks to the reader of my experience who very kindly pointed out my error!!!! Despite having a brush with the big C last year (I finished chemotherapy in January) I have been very fit and healthy during my 61 years! A few weeks ago I started having palpitations, hence a visit to the doctor revealed high blood pressure and cholesterol reading of 9.9!!! Shock, horror. He informed me that it was genetic and prescribed Simvastatin 40mg and Bendroflumethiazide 2.5 mg daily. Not being satisfied with the enclosed leaflets I have looked up more info. on the net. Should I have done this!!! After reading some of the posting on the site I am feeling a bit apprehensive. Last night I had a terrible night couldn't sleep for the pains in my legs and a bit nausea this morning. But I need to be sensible, I really don't have any choice but to take these drugs just hoping that I won't have to stay on them for the rest of my life and I don't get any of the side effects that some of you have suffered. I also wonder if the chemotherapy could have caused by raised cholesterol? Hope to keep you posted and would welcome any comments!
