You need to speak with your doctor about the possibility of an allergic reaction to this medication. Hives are a sign of this, and should be reported to your doctor right away. Furthermore, since you have developed joint (or muscle) pain,and fatigue, this is an adverse reaction to this medication, and you need to speak with your doctor as soon as you can about prescribing a different medication. Severe muscle damage and kidney problems have also been associated with this medication. However, alcohol increases your risk of developing a serious side effect. You should try to avoid alcoholic beverages if possible when on this medicine. I do believe all of your symptoms are directly related to the zocor and this is something that should be addressed by your doctor soon. Thanks so much!
