It sounds uncomfortable to have persistent pain in your neck, lower ear, and shoulder along with some pain when swallowing and headaches during fasting. These symptoms could be related to muscle strain, inflammation, or possibly an infection or nerve irritation in the neck area.

• Since the pain has lasted a month and involves swallowing difficulty and headaches, it’s important to have a thorough evaluation by an ear, nose, and throat (ENT) specialist or an orthopedic doctor specializing in the neck and shoulder.
• They may recommend imaging or physical examination to identify any underlying issues such as muscle or joint problems, nerve involvement, or infections.
• Meanwhile, avoid heavy lifting or strenuous neck movements, stay hydrated, and try gentle neck stretches if tolerated.
• If you develop worsening pain, fever, difficulty swallowing, or neurological symptoms like numbness or weakness, seek urgent medical care.
