What to do if nothing helps my sinus infection! what are my other options?

Sinusitis: It depends on what you mean by nothing. If you have had confirmation by ENT and Sinus CT scan, multiple courses of antibiotics, test for fungal sinusitis, allergy testing and treatment with antihistamines, leukotriene inhibitors, immunotherapy, sinusotomy or endoscopic sinus surgery for relief of anatomic obstruction then there is nothing else you can do. If not then please see ENT.
