It depends on the sentence structure. If "recently" is modifying the rest of the sentence, then use a comma. If it is modifying a specific verb, do not use a comma. Example 1: Recently, I discovered that I'm not as wild about blueberries as I used to be. Example 2: I recently discovered that I'm not as wild about blueberries as I used to be.
