Hello are having pain all over body with tiredness, sneezing, blocked nose with running nose and breathlessness, all these symptoms are an indication of flu or common cold or upper respiratory infection. When such case visit my clinic with these symptoms I usually advise them to take montelukast+levoceterizine tablet once in day with levofloxacin 10 mg / kg body weight, once in day with paracetamol 10 mg / kg body 2-3 times in day for 5-7 days. Within this period patient respond this treatment. You mentioned that there is severe pain on the left side of body at a particular place but you didn't mention the site so very difficult to say about this pain. If this pain is in the lung (left side) may be due to pneumonia. Diagnosis can be confirmed by X-ray chest. If pain is not in lung area then take this treatment. Good luck.
