Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have severe cold, cough, runny blocked nose which seems to be due to upper respiratory tract infection is caused by virus known as common cold infection. Need not worry about it. Nauseating feel and diarrhea occurs mainly as a coinfection due to impaired immunity of body, and it could be side effect of medications if any you have taken. I would suggest you to take few preventive measures such as avoid fried and spicy food. Apply mist humidifiers in room. Take multivitamins to booster your immunity. Visit ENT specialist once if symptoms keeps on persisting and get it examined and start treatment accordingly. You should take antihistamine Chat Doctor.  You should use decongestant nasal sprays like Origin along with antibiotic such as Amoxiclav.  Use throat lozenges. You should do saltwater gargle as well. Hope your concern has been resolved. Get Well Soon. Best Wishes,
