Upon further research I think your answer was not entirely correct. It seems HIV itself can cause Myopathy and Myalgia with elevated creatine kinase.
"Peripheral neuropathies are common in patients infected with HIV. They occur at all stages of illness and take various forms, as follows:
Myopathy: This may range in severity from an asymptomatic creatine kinase elevation to a subacute syndrome characterized by proximal muscle weakness and myalgia."
Welcome back to the forum. First off, yes, there is an HIV-associated myopathy as well as an AZT-associated myopathy, both of which are associated with elevated CPKs. The symptoms can include pain and aching in the muscles, usually thighs and shoulders, as well as weakness, with difficulty when rising from a chair or reaching above the shoulders. It can occur at any CD4 cell count. The clinical features related to the symptoms include mild to moderate muscle tenderness, weakness in the proximal muscles (those closest to the body, i.e. upper arms and legs) a normal sensory exam and normal reflexes. An EMG (electromyelogram) is diagnostic. In general, I do not go into this level of detail about specific diagnoses due to constraints of time and the scope of this forum, but since you asked, there you have it.
Regarding my original advice, please note I was responding to your complaints of being "constantly tired but mostly achy." Without knowing much more about your condition, such as how elevated your CPK really is, I was reluctant to go into great detail about very specific conditions, and suggested that your write back with additional information (lab test results, etc.) if you continued to have problems. My evaluation of your condition and advice to you remains unchanged!
