How do you know you have a clogged milk duct?

I recently weaned from bf'ing.  I did it gradually over the past couple weeks and dropped bf'ing and pumping completely 4 days ago.  My right breast feels fine and back to normal but my left still feels a little full and hard.  I have been massaging in the hot shower in the mornings and a little milk expresses out.  Do I have a clogged duct?  How can I fix this without pumping because I don't want to produce more milk.  Also, when is it safe to stop wearing breast pads in fear of leaking until I am compltely dried up?  TIA!
