HIV can cause muscle pain, known as myalgia, which is a common symptom of acute HIV infection. This pain can manifest in various ways, including muscle aches, joint pain, and abdominal cramping. The pain may be more common with age or in those who previously took older HIV drugs. It is important to note that other conditions, such as injuries, influenza, or fibromyalgia, can also cause muscle aches. Therefore, an HIV test is necessary to confirm the presence of the virus. HIV-associated myopathy can be caused by the virus itself or by certain antiretroviral medications, and it may be part of an immune reconstitution inflammatory syndrome (IRIS).

What You'll Learn
HIV-associated myopathy
The mechanism by which HIV leads to inflammatory myopathy is not fully understood. However, it is proposed that a T-cell mediated and MHC-I-restricted cytotoxic process triggered by HIV may be responsible. HIV-associated myopathy has also been described as part of an immune reconstitution inflammatory syndrome (IRIS). Certain antiretrovirals, such as zidovudine (AZT), may lead to toxic myopathy by impairing mitochondrial function.
The diagnosis of HIV-associated myopathy can be challenging. Electromyography (EMG) is a sensitive diagnostic test, revealing a typical myopathic pattern similar to that seen in seronegative polymyositis. The presence of objective muscle weakness, elevated serum CK, myopathic findings on EMG, and a myopathic muscle biopsy can lead to a definitive diagnosis. However, the prognosis and best course of treatment for HIV-associated myopathy are not well established due to its rarity. Corticosteroids have shown some success in treating this condition, with over half of patients in one case series attaining complete remission and discontinuing therapy after an average of 9 months.

HIV-related muscle pain
Muscle pain is a common symptom of acute HIV infection. Myalgia, or muscle pain, usually begins two to four weeks after exposure to the virus and can last for several weeks. The pain can be felt in the legs, back, and hips, and may feel similar to muscle soreness after exercise or sleeping in an uncomfortable position. However, unlike these types of muscle aches, myalgia associated with HIV lingers for an extended period.
HIV targets the immune system, making individuals more susceptible to infections and increasing the likelihood of experiencing pain. Untreated HIV can also lead to peripheral neuropathy, a neurological disorder affecting the peripheral nerves. Additionally, specific antiretroviral drugs used in HIV treatment, such as zidovudine (AZT), have been associated with toxic myopathy, resulting in muscle weakness or exercise intolerance. Other medications, such as statins for high cholesterol, have also been linked to muscle pain around the joints.
Managing HIV-related muscle pain can be challenging due to the potential interactions between pain relievers and HIV treatments. However, several options are available, including both medication and non-drug therapies. Doctors can prescribe pain medications to reduce inflammation and improve quality of life, such as acetaminophen, aspirin, and ibuprofen. Topical treatments, such as gels, creams, or patches, can also be applied to specific areas of muscle pain. It is crucial to consult a doctor before taking any over-the-counter medications to ensure their compatibility with HIV treatments.
Non-drug options for managing HIV-related muscle pain include heat or cold therapy, applying heating pads or ice packs to sore joints, and joining chronic pain support groups. Additionally, antiretroviral therapy (ART) drugs can help control the virus and may provide some relief from muscle pain. In some cases, doctors may recommend switching to alternative medications if specific drugs are causing muscle pain.

HIV drugs causing muscle pain
HIV itself can cause muscle pain, also known as myalgia. This is a common symptom of acute HIV infection, which can occur 2 to 4 weeks after exposure to the virus. The muscle pain can be felt in the legs, back, and hips, and may feel similar to post-workout soreness. However, unlike post-workout soreness, myalgia can linger for several weeks. Aside from muscle pain, acute HIV infection can also cause fever, rash, and other symptoms of illness.
Some HIV medications can also cause muscle pain and discomfort. Older HIV drugs, in particular, have been associated with muscle pain and other side effects such as nausea, diarrhea, stomach cramps, and headaches. In some cases, the pain may be due to the immune system attacking the joints as a result of the treatment revving up the immune system. Certain antiretroviral drugs may also lead to toxic myopathy through impairment of mitochondrial function. For example, Zidovudine (AZT) myopathy can manifest as fixed weakness or exercise intolerance, which resolves within months of withdrawing the drug.
If you are experiencing muscle pain due to HIV or its treatments, there are several management options available. Changing or stopping the problematic drug may solve the muscle pain, although this may not always be feasible. Over-the-counter medications such as Aspirin and acetaminophen (Tylenol) can help manage the pain, but they do not address the underlying cause. Doctors may also prescribe medications to reduce painful symptoms, including nonopioid options that have a lower potential for addiction or dependence. Additionally, nondrug options such as heat or cold therapy can be used to manage joint and muscle pain.

HIV-associated arthritis
The arthritis associated with HIV can affect the large joints of the upper limbs and knees in an asymmetric pattern. It can usually be managed with rest, NSAIDs, and paracetamol, although severe pain may occasionally occur. Imaging studies reveal changes in the small joints of the feet, with erosion and adjacent new bone proliferation. These changes can lead to progressive deformity and severe arthritis in the larger joints.
Psoriatic arthritis is also more common in people with HIV and can worsen with the progression of the infection and depletion of CD4+ T-cells. It may affect the spine and sacroiliac joints or cause peripheral small joint disease, resulting in the classic appearance of "sausage digits". Rheumatoid arthritis (RA) has also been associated with HIV, although there is ongoing debate about its relationship with the virus. Some reports suggest that RA patients may go into remission with HIV infection, while others indicate that RA may flare up or arise during the immune reconstitution inflammatory syndrome.

HIV-related chronic pain
The causes of HIV-related chronic pain are not yet fully understood, but it is thought that the virus itself, as well as HIV drugs and other medical conditions, may contribute to nerve damage and inflammation that can result in pain. Older HIV drugs such as d4T (Zerit) and ddi (Videx) were associated with peripheral neuropathy and are rarely used today due to their side effects. Other HIV drugs can also cause abdominal pain and inflammation of the pancreas (pancreatitis). In addition, people with HIV are vulnerable to co-infections, such as bacterial infections and herpes viruses, which can cause pain.
Psychosocial factors have also been identified as strong influences on HIV-related chronic pain. Stigma and mood disturbances related to HIV can negatively impact health-promoting behaviours such as medication adherence and patient-provider relationships. Illicit substance abuse, including opioid dependence, is more common among people with HIV and can increase pain symptoms and complicate pain management.
The first step in managing HIV-related chronic pain is to identify the type and cause of the pain. However, it is important to note that there is currently no perfect treatment for chronic pain in HIV, and the development of best practices for pain management in this population is impeded by the lack of understanding of the underlying causes.
