Thanks for your question on Healthcare Magic. I can understand your concern. Swollen lymphnodes, cough, fatigue etc are symptoms of bacterial upper respiratory tract infection (URTI). You need broad spectrum antibiotic like levofloxacin or azithromycin. These are prescribed drugs, so you need to consult your primary care physician. Along with antibiotic, you will need antihistamine and anti inflammatory drugs. Do warm water gargles 5-6 times a day. Drink plenty of fluids orally and keep yourself hydrated. Don t worry, you will be alright with all these in 1 week. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
