clogged duct/mastitis

how can I heal this at home?? (NOTE: NOT breastfeeding, haven't breastfed at all with this baby, he's 6wks old) my right breast has been sore since yesterday. this morning I kept waking up shivering then sweating, horrible headache & body aches with nausea. my breast is really tender to the touch but isn't red so not sure if it's clogged duct or mastitis either way how can I get rid of it?

**do you make a Dr appt with family doctor or obgyn?**
