Chronic sinusitis, now flaring thanks to a cold. temp 99.7, post-nasal drip sore throat. must use antibios or not? history of c-diff makes me nervous.

Sinusitis: Try flonase 2 sprays in each nostril for a week, hot shower to the face, hot rag to the face, soothing beverages, ibuprofen 800 q 8 hours for symptomatic relief. If you spike a fever or have pressure in your sinuses that causes headache or discomfort see MD. You should also get expert consultation/imaging coordinated by an expert in ENT Surgery given chronicity of your Sx. Good luck.
