Thank you for the query. I would like to know your age and whether you suffer from any associated comorbidities like Diabetes mellitus, Hypertension or Thyroid dysfunction. As per the history provided, you are suffering from dry cough, bodyache, swollen glands, coryza and occasionally high grade fever (body overheating may imply that), for a period of 2 days. Your symptoms are more in favour of a viral infection. In a sunstroke you will get other symptoms like nausea, vomiting, severe cramps, dry skin, dizziness and severe headache. I would advise you to take bed rest for a few days and drink plenty of water and fluids (avoid alcohol). If your body gets overheated you can go for cold or tepid sponging. A nutritious diet is advisable, and if you are a smoker, you must abstain from smoking (this irritates your respiratory tract and aggravate your cough). If you have nasal congestion and throat irritation, steam inhalation may help. In case of severe bodyache, acetaminophen may be taken (after consulting your physician). Please monitor your urine output. If you develop any of the symptoms mentioned above or your symptoms do not subside in another couple of days, please consult your physician, since you may need a thorough physical check up and a course of antibiotics may be needed. Hope this helps you out.
