Brief Answer: Flu is unlikely... Detailed Answer: Hi, In the absence of fever, cough and cold is unlikely to be flu or any other infection. The cause may lie in your sinus (sinusitis), throat or stomach (GERD). Allergies may be contributing too. In all probabilities HbsAg carrier state wouldn't be responsible. I advice you using antibiotic over the counter for such problems. You may try a course of antihistamines, cough formulas along with proton pump inhibitor drugs for a week or two and see if you get better. The drugs can be prescribed by your local physician or ENT surgeon. In the meanwhile you can try steam inhalation and 5ml benadryl syrup three times a day at home until you meet the specialist. I wouldn't investigate you if clinical examination is unremarkable. Therefore visit the doctor before you plan any testing on yourself. Hope this helps. Let me know if you need clarifications.
