Viral is a word whose meaning far predates its current Internet usage. A health issue is viral when it’s caused by a virus, which means that the inactive population in your body is a sort of self-replicating molecular machine, not a bacterium.
Why does this matter? Viral symptoms cannot respond to antibiotics, as there is literally nothing “biotic” to kill. Viral issues, like the common cold, are best treated with a wait-and-see strategy, as described here.
When sinusitis keeps getting worse over several weeks, and is accompanied by fever and/or cramping, then it may have graduated into a bacterial infection. For the best treatment of bacterial sinusitis in Los Angeles, contact the LA Sinus Institute.
