The main symptoms of TMD (temporomandibular disorder) can vary depending on the specific condition, but some common symptoms include:

• Pain or tenderness in the jaw, face, neck, or around the ear.
• A popping or clicking sound when opening or closing the jaw.
• Limited jaw movement or difficulty opening the mouth wide.
• A locked jaw that is difficult to open or close.
• Tiredness or soreness in the jaw muscles.
• Headaches or earaches.
• Dizziness or ringing in the ears (tinnitus).
• Facial pain or swelling.
• Toothaches or tooth sensitivity.
• Neck and shoulder pain.
• Difficulty speaking or swallowing.
• Bruxism (teeth grinding) or clenching.
  

It's worth noting that some people with TMD may have no symptoms at all, or their symptoms may come and go. Some people might have severe pain, while others might have mild discomfort. In some cases, symptoms may be caused by a combination of factors and may not be directly related to the TMJ itself, such as headaches or neck pain. An accurate diagnosis from a healthcare professional who specialized in TMD is important to determine the underlying cause of the symptoms and provide the appropriate treatment.
