High cholesterol levels. Way out of it?

I am 27 years old male and few months back during my regular checkup I was diagnosed with High cholesterol levels of LDL - 190 , HDL - 40 , Total cholesterol - 280 , Triglycerides - 90 , VIT B12 - 80.  Doctor prescribed me with Crestor 20 mg and I took it for 3 months which reduced my Ldl count to normal but significantly increased my SGPT and SGOT levels. Then I took Prelipid Abbott company med which brought back my cholesterol levels to normal . But while taking these medicines I had constant muscle pain and anxiety and not a good feeling at all . I am regular lawn tennis player past 3 years . My father , uncle all have a history of high cholestrol. I want to know if I really need to take a statin or Prelipid for my whole life to keep my cholesterol level normal . I dont  feel like taking medicines but when I stop them cholesterol levels jumps again . Please advice me what should I do and is medication really necessary . Is there any other way out of it ?? Please advice me.
