Brief Answer:
Sinusitis needs treatment with antibiotics.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
I do feel your sinus infection is not adequately treated. Such persistent sinus infections often cause recurrent headache. You require a full course of good antibiotic (such as a combination of Amoxycillin and Clavulanic acid or Gemifloxacin), a mucolytic (such as Ambroxol or Bromhexine) to reduce the viscosity of the secretions, saline nasal spray to help in clearing of the mucus, a potent steroid nasal spray (such as Fluticasone) and an anti-inflammatory medicine. All these are prescription medicines and can be taken only after physical examination. So, kindly get these medicines prescribed by your doctor.

Apart from this you need to do steam inhalation 3-4 times a day, drink plenty of warm water, and avoid coffee, smoking and chilled food.

If you feel your intestines are sensitive for the antibiotics you can use probiotic which helps in maintaining the natural flora of the intestines and reduce loose stools.

Even after using the above medications if you are not improving, you need to get nasal endoscopy done to examine the inner part of the nose and CT scan of the paranasal sinuses if required.

Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.
Dr. Rakhi Tayal.
