If you are taking Storvas-EZ, then you are not just consuming atorvastatin but ezetimibe as well since this brand is a fixed-dose combination product of two medicines. Unfortunately, the side effects of the two medicines get added up. Both the medicines can cause rashes and joint pains individually. For a variety of scientific reasons, it is not a very good idea to prescribe combination products. If at all two medicines are required, then they should be taken separately so that dose can be adjusted and side effects monitored. Also, you have not given the reasons (diagnosis) for taking Storvas-EZ as well as cholesterol and triglyceride readings. As a first step, the therapy should be reviewed and if at all necessary, only atorvastatin (such as Atorva) can be prescribed.
