What causes pain on the left side of the face?

Generally, pain on the left side of the face may be caused by environmental stimuli, poor posture, trigeminal neuralgia, temporomandibular joint pain, herpes zoster, and other factors. It can be improved through local heat application, appropriate massage, medication, and other methods. It is recommended to visit a regular hospital and follow the guidance of qualified physicians. Detailed analysis is as follows:

1. Environmental Stimuli

Remaining in a cold environment for a prolonged period may cause blood vessel constriction and nerve irritation, leading to pain on the left side of the face. Applying local heat can promote blood circulation and help relieve the pain.

2. Poor Posture

Maintaining the same posture for an extended period might affect local blood circulation and cause facial pain. Improving posture and performing appropriate massage can help alleviate the pain.

3. Trigeminal Neuralgia

Trigeminal neuralgia occurs due to compression, injury, or inflammation of the trigeminal nerve, which may cause facial pain on the left side. Medications such as Pregabalin Capsules or Ibuprofen Tablets may be used under medical supervision for treatment.

4. Temporomandibular Joint Pain

Temporomandibular joint pain typically results from issues with the chewing muscles or the temporomandibular joint itself, leading to facial pain. Conservative treatment is generally recommended. If necessary, wearing a temporomandibular joint occlusal splint can help eliminate jaw abnormalities, relieve muscle tension, and stabilize the joint.

5. Herpes Zoster

Herpes zoster is usually caused by a viral infection and often presents as pain on the left side of the face, accompanied by symptoms such as fatigue, low-grade fever, and headache. Consultation with a physician for medication such as Acyclovir Tablets or Mecobalamin Tablets may help alleviate symptoms.

If the pain persists or worsens, timely medical attention is advised. During the recovery period, maintain a light diet and increase the intake of vitamin-rich vegetables and fruits, such as tomatoes, carrots, grapefruits, and apples, which can enhance immune function and promote overall health.
