I have had a gnawing pain in one area of my left breast for the last 2 days. DD now 10weeks have started sleeping 6-8hour stetches at night and I think this started after the fullness of the first few nights of this. No redness visible and can't feel any lumps but the let down feeling more pronounced from there as well. Do not feel unwell but the pain is irritating and persistent. Could it be a blocked duct and if so how do I get rid of it?
