Hi thanks for your question. Mostly according to history you probably have acute viral infection of respiratory tract.Such mentioned symptoms can occur as constitutional symptom by viral infection. Do your CBC .If lymphocytes more then viral is the cause or if high neutrophilia then bacterial , if high eosinophil then allergic cause. If fever increasing , CBC showing neutrophilia and cough is there chest x ray done for rule out consolidation as in pneumonia. For block nose antihistaminic and oxymetazoline like decongestent can be taken..steam inhalation also good Avoid oily food for few days. I hope your concern solved. Take care....
