In pain,please help!

I'm exclusively pumping and having major issues. I can't get all my milk out with the pump itself and am on my way to mastitis! I have a Spectra S2 and an medela freestyle but neither one can empty me. I get so much out through hand expression after I pump for 15-20 min so I know I'm backed up. Anyone else have this issue or know a way to resolve it? I'm miserable and don't have the time to pump AND hand express due to having a 19month old at home as well who is really active!
