Help!! Clogged duct😭

So my left boob hurt ALOT a few days ago. I am EP’ing and I pumped for a good 25 minutes to try and unclogged the duct that was giving me pain. Fast forward, I have no more pain. But it still feels like I have a clogged duct. I’ve done a hot shower, heating pad. And it still feels hard. With my right boob, I’m already at 2 Oz in 12 minutes while my left is barley over an Oz. I’m scared I’m going to develop mastitis if I can’t get this unclogged.
