Hi,
Noted your history of light headedness, moping headache for 48 hours, strange heartbeat in middle of night awakening you, pain in left
clavicle area.
The most probable cause can be a viral infection as your symptoms indicate.
This can cause
myalgia, muscle spasm and so on.
Hence I would advise you the following in such a situation:
Consult your Doctor as a proper clinical evaluation and examination can give a proper clinical diagnosis.
Supportive investigations helps further.
This will allow the most appropriate symptomatic and definitive management. Like
Hypertension can be cause of your headache and needing anti-hypertensive medications.
Take rest, follow up well.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
