If recently is a clause on it's own then you use a comma to seperate and to make it clear that you are setting the scene for the following clause but if recently is used within a clause then no.
Example:
Recently, I have not been feeling hungry.
I have recently graduated from University.
,but
after it... ~but,~
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.
Do NOT put a comma before subordinating conjunctions such as unless, if or because.
