Clogged duct or mastitis? Maybe something else?

Yesterday I came down with terrible body aches and my left boob aching but no redness so I emptied my boobs by pumping and took a hot shower and felt better although that boob was still sore under neath, I could really feel it if I lifted my arm. So fast forward 1am when my son(4 weeks old) wakes up to eat I have horrible body chill and aches and this time a slight fever of 99.8. So I took Motrin and drank lots of fluids then went back to bed after three hours of being in pain from body aches. So now I wake up and I’m okay again? My boob feels a little better this morning but I’m confused on what this could be? Any advice or anyone have this?
