Hello, Your neck pain may indeed be due to a muscle strain or “sleeping wrong,” especially since it started when you got out of bed and is causing severe restriction in neck movement. However, what concerns me is the sudden swelling of only your left foot/ankle/toes occurring around the same time. These two symptoms may be unrelated, and the leg swelling should not be ignored.
Possible causes of the neck pain: • Acute neck muscle spasm (torticollis) • Muscle strain from sleeping in an awkward position • Cervical joint inflammation
Possible causes of the one-sided leg swelling: • Local injury or inflammation • Venous circulation problem • Deep vein thrombosis (blood clot) – especially if the leg is painful, warm, red, or increasingly swollen • Less commonly, infection or lymphatic blockage
Since unilateral leg swelling is not usually caused by a simple neck strain, I would recommend an in-person medical evaluation within the next 24 hours.
Please seek immediate medical attention if: • The leg becomes red, hot, or very painful • The swelling rapidly worsens • You develop chest pain, shortness of breath, dizziness, or fainting
Prescription/Advice: • Tab Paracetamol 650 mg every 6-8 hours as needed for pain (maximum recommended daily dose as per package instructions). • Continue warm compresses to the neck 15-20 minutes, 3-4 times daily. • Gentle neck movements only; avoid sudden twisting. • Elevate the swollen leg while resting. • Do not massage the swollen leg until the cause is known. • Arrange a prompt evaluation by a physician, as you may require examination and possibly an ultrasound of the leg if the swelling persists.

Hello
The neck pain may indeed be from sleeping in an awkward position, causing a muscle strain or spasm. However, the new swelling of only one leg (left ankle and toes), especially when it appeared around the same time and is still present, is not something that should be assumed to be related to sleeping wrong.
One-sided leg swelling can have several causes, including a blood clot in a deep vein (Deep Vein Thrombosis), inflammation, infection, or less commonly a problem with lymphatic or venous drainage. Because a blood clot can be serious, it is important to consider it, especially when swelling is new and affects only one leg.
For the neck pain, gentle movement, heat, and over-the-counter pain medication (if you can safely take it) may help. Avoid forcefully stretching the neck. For the swollen leg, elevate it when resting and avoid prolonged sitting or standing.
However, I would recommend that you seek medical evaluation promptly—preferably within the next 24 hours, and sooner if possible—because of the unilateral leg swelling. A clinician may need to examine the leg and determine whether testing such as an ultrasound is needed.
Seek urgent or emergency care immediately if you develop shortness of breath, chest pain, coughing up blood, rapidly increasing leg swelling, redness/warmth of the leg, severe headache, weakness, or numbness.
The neck pain alone would most likely suggest a muscle strain, but the combination of severe neck pain and new one-sided leg swelling deserves prompt medical assessment rather than home treatment alone.

The combination of severe neck pain with markedly limited movement and new swelling of the left foot, ankle, and toes developing around the same time is not typical of simply “sleeping wrong” and warrants prompt medical evaluation. While the neck pain could be due to a muscle strain or spasm, the associated unilateral leg swelling raises concern for other conditions such as inflammation, infection, a circulation problem, or less commonly a blood clot, especially if the swelling is significant or worsening. Fatigue further supports the need for assessment. Until reviewed, the patient should rest, keep the affected leg elevated when possible, stay hydrated, and avoid strenuous activity. Because new one-sided leg swelling can occasionally indicate a serious condition, the patient should seek medical attention promptly, especially if there is redness, warmth, increasing swelling, chest pain, shortness of breath, weakness, numbness, fever, or worsening neck pain.
