White coating on tongue

I just noticed today that my tongue has a white coating that can be scraped off. The white coating is "grainy" and creamy but the surface of my tongue under the coating is not sore. I just finish my 5-day course of Metronidazole 500mg 3x a day. Is this a common side effect, or is this something that I need to worry about?

yes, metronidazole can cause oral thrush.

not, oral thrush does not cause swollen lymph nodes.

if you THINK you have oral thrush, ask your doctor for a candida culture (oral swab).
