DEAR DOCTOR K: My doctor won't give me an antibiotic for my sinus infection. So what can I do to feel better?
DEAR READER: Most cases of sinusitis are caused by viral infections. Viruses are bulletproof to antibiotics. All antibiotics can do in this case is cause side effects. So, the best course of action for occasional sinusitis is to use self-care steps to ease symptoms while the body clears the infection.
