Hi, Thanks for using the HCM. I am happy to address your questions, some of the most common atorvastatin side effects are headache, diarrhea, and muscle pain, other common problems associated with the medication include joint pain and unexplained rash. Joint pain was seen in up to 5.1 percent of people taking the medication, depending on the dose. It has been beneficial from using pain relief medicines like anti-inflammatory. Moist heat (such as a warm bath or shower) or dry heat (such as a heating pad) placed on the painful area of the joint for about 15 minutes may relieve joint pain. In some cases, cold packs (a bag of ice or frozen vegetables wrapped in a towel) can relieve pain or numb the sore area. If you have poor circulation, do not use cold packs. Water therapy in a heated pool or whirlpool may also relieve joint pain and stiffness. If it is not subsiding will recommend you to visit your clinician for alternative anti-hyperlipidemic drugs. Hope I have answered your query. If you have any further questions I will be happy to help. Thanks
