Hello, Meloxicam does not cause withdrawal effects. If meloxicam had achieved substantial pain control and was stopped suddenly then the pain may recur and cause symptoms. Since you ve started Atorvastatin though, another - perhaps more likely cause - is a side effect. Atorvastatin is well-known for causing diffuse body aches particularly when combined with other drugs like the fibrates or certain antibiotics and antifungals. You can check your creatinine phosphokinase (CPK) levels to find out although in some cases the CPK levels may be normal even when atorvastatin is the cause. It would still be useful to know. In such cases, I usually advise my patients to stop the statin and proceed to CPK testing. Be warned though that sometimes the pain caused by the statin may take many days to subside. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Panagiotis Zografakis, Internal Medicine Specialist
