Repatha vs. zetia and statin

I am currently taking pravachol for high cholesterol. I have also taken crestor but when it gave me mild muscle aches my doctor immediately switched me to pravachol. Pravachol has done nothing and my cholesterol is higher than ever. My doctor wants to put me on Rapatha. I really don't want to do the injection plus it is expensive. Would it be reasonable to ask if I could return to taking crestor and also take zetia to see if that will lower my cholesterol and LDL?
