Clogged duct, tissue damage or beginning of the dreaded mastitis

Last night during my midnight pump session I think I may have found a clogged duct or injured my breast tissue🙄. my right breast doesn't always sit right in my flange and I have to rearrange it/ apply pressure to sometimes hold it. I think unknowingly until too late I was pressing my flange hard into my left breast and didn't notice that my suction was on a higher suction setting till I was almost done. My left breast has been EXTREMELY painful since. I've never had pain while nursing or pumping. It's been awful! I can't exactly locate a clogged duct like online says I should be able to. I think it's a clog as my right breast isn't painful at all. I've latched baby as often as he would and pumped afterwards to make sure I was fully empty, heating pad, hackka with Epsom salt, vibration, ibuprofen,massage. It's more so underneath. Any suggestions or thoughts?
