Headache on one side accompanied by swelling on the same side of the face

One-sided headache accompanied by facial swelling may be caused by conditions such as migraine, cluster headache, or mumps, and treatment should be based on the specific cause. Details are as follows:

1. Migraine

This condition is usually associated with genetic, endocrine, and metabolic factors. Most patients may experience recurrent, one-sided pulsating headaches, often accompanied by nausea and vomiting. Under a doctor's guidance, medications such as metoprolol succinate extended-release tablets or naproxen tablets can be used for treatment.

2. Cluster Headache

This is typically a primary neurovascular headache characterized by unilateral head pain along with facial swelling, occurring in repeated and closely clustered episodes. Treatment may include lidocaine aerosol (Ⅱ) or verapamil hydrochloride tablets, taken according to medical advice.

3. Mumps

Usually caused by bacterial infection, commonly due to Staphylococcus aureus or streptococcus. Persistent inflammatory stimulation of the parotid gland may lead to symptoms such as fever, swelling, and pain in the parotid area. Under a doctor’s supervision, medications such as Pudilan anti-inflammatory tablets or Qingre Jiedu oral liquid may be used for treatment.

In addition to the above causes, one-sided headache with facial swelling could also result from trigeminal neuralgia, hypertension, cerebral ischemia, or other conditions. It is advisable to maintain a light diet and consume plenty of fresh fruits and vegetables.
