Muscle aches, sprains, strains, TMJ, and joint pain are common and often result from overuse, minor injuries, or the natural wear and tear associated with osteoarthritis. Most cases can be safely managed with rest, supportive care, and time. However, pain that is sudden, severe, worsening over time, associated with swelling, redness, warmth, fever, inability to move the joint or limb, numbness, or signs of infection may indicate a more serious condition. If you experience these symptoms or if your pain does not improve with basic care, it is important to seek an in-person medical evaluation for further assessment.
