Itchy muscles are a common sensation, particularly during physical activity. This sensation, also called "pruritus", is often felt under the skin and isn't always relieved by scratching. Itchy muscles can occur during or after exercise due to increased blood flow to working muscles. This can also be a symptom of an underlying medical condition, such as multiple sclerosis or shingles. In some cases, itchy muscles occur with pregnancy or as a side effect of medication.
Itchy muscles can also be a way that your body is processing stress from working out. When your blood vessels are inflamed, the vessel walls change and can restrict blood flow. All of this may send signals to the nerves in your muscles and cause your muscles to itch. Case studies have shown that exercise can cause itchy muscles, and it's a common experience among runners.
Scientists are researching neurological conditions and what causes nerves to respond the way they do. Studies are finding overlap in the neural responses of pain and itchiness, which could result in breakthroughs for treating both chronic pain and itching.
