Help with Silicone tunnels in my ears?

So basically I stretched my ears about 4 hours ago from 16mm to 18mm then to 20mm and I have put the 20mm Silicone tunnels in about half an hour after leaving the 20mm stretchers in. Now obviously they hurt when I did this but when I finally got the tunnels in, the pain stopped a bit and is now just throbbing. They are swollen and I can't get the tunnels out because of this reason. Now I'm wondering if the tunnels will be easier to get out tomorrow from the swelling (hopefully) going down as I want to clean them everyday? and also because I have read a lot online about skin fusing with the silicone after I had ordered the tunnels online so I am very paranoid.
