I used to take crestor (rosuvastatin) but was one of the few who had muscle pain as a side effect , my question is will all statin meds have side effect?

Not necessarily.: Some r combinations of meds, some r only 1 statin. Trial ; error. If u switch, report immediately any such symptoms. Also don't start until the aching clears.

Not necessarily: Not necessarily, but needs to be monitored closely, with cpk, aldolase and clinical evaluation. However, if muscle damage was considered severe by physician, probably best to avoid the class of med.
