My husband has been battling a sinus infection. what can i do to help?

Antibiotics: The term battling means it has not been responding to conservative measures. A course of antibiotics and even steroids would be beneficial.

Maximize OTC meds: Often even in cases where antibiotics are necessary, we can alleviate the annoying symptoms of sinusitis with otc meds. A very useful regimen is using a salt water rinse 2 a day (ex neilmed sinus rinse). Also Mucinex (guaifenesin) max strength 2x day will also help most of the time. Another adjunct is to use a anti-histamine medication as well. However, good these are, often you will need antibiotics.
