Here are a few ways you can differentiate between a joint or muscle.
1. Identify the location of the pain - If the pain is isolated to a specific area, it may indicate a muscle injury, while pain in and around the joint may indicate joint or ligament damage.
2. Determine the type of pain - Muscle pain is characterized by a sharp, burning or dull aching sensation. Joint pain, on the other hand, may feel stiff, achy or creaky.
3. Analyze the range of motion - If there is a loss of range of motion, it may indicate joint damage, while muscle damage may not restrict mobility as much.
4. Notice any swelling - If there is swelling around the site of the pain, it may be an indication of joint injury or inflammation.
5. Consider the cause of the injury - If the injury occurred during a physical activity that requires repetitive use of a specific muscle or joint, it may more likely indicate a muscle or joint injury, respectively.
