... cramps at night while I sleep,fingers cramps every now and then,numbness and tingling in my feet when I stand on them for any length of time and flushing red face everyday which is my biggest side affect that bothers me the most.I'm going to see my doctor for my yearly physical and wanted to know if I should ask him to prescribe me a liver enzyme function blood test and a kidney test since I've been taking a statin now for almost 1 year?
