Hi Mandi,
It's hard to tell from a pic, since there could be so many things wrong, but I enlarged your pic and brightened it up a bit. If I had to guess, I'd say you've got fecal erosive dermatitis. That's the fancy way to say your barrier ring isn't sealing well. You have a flush stoma, which isn't a good way to start out your ostomate journey, but hopefully your stoma will extend a bit more and make things easier. I'm surprised your ostomy nurse isn't all over this, and although there's a lot of stuff they can be clueless on... this isn't one of them.
You didn't give us details on how frequently you change your barrier or why. The first thing you need to do is figure out what's going on with your ring. Is there output under the ring when you take it off, meaning output between your skin and the ring... or is it just red and angry? If no output, then you probably are having an allergic reaction to the ring material. But since the redness isn't an exact circle copy of the shape of the ring... I don't think it's that. But get some rings from different vendors to have on hand. If you do find output under the ring, you've found your problem. You definitely need a convex barrier with your stoma, so if you're not using one... get you some!
As for the pain and inflammation... it's not going to go away until you find and fix the source. For now, what you can do is get some Domeboro soaks... they're packets of powder that come in a box and can be found at most drug stores or online. I know CVS has them, but not sure of the other chains. They may have a generic, which is fine, just make sure it's an Aluminum Acetate Astringent powder. You mix one packet in 2 ounces of water... it says 4 oz, but 2 works better. You soak a couple of paper towels in it and then place them over your stoma. I'd go about 4 towels thick and let it sit there for at least 15 minutes... longer if you can. This will calm your skin down. After you remove them, gently wipe your skin with warm water on a paper towel, and then dry your skin completely. When you apply your new ring, make sure you get it as close to your stoma as you can, leaving as little skin around it exposed. I know it's hard when your stoma is flush, but do the best you can. It helps to warm your skin and the ring with a hair dryer (don't go nuts) and then install the ring. After that, install your barrier and hold everything with your hand over it to keep your body heat in. Some do this for a minute or so and then install your bag and attach your belt. Cinch your belt up snug, but not too tight or it will distort the barrier and you'll have a leak.
Now the important stuff. You need to remove your barrier/ring BEFORE it leaks again and change it again doing the same thing I explained above. When you do change it, make sure to look at the ring and your skin very carefully when you remove it. Note where your skin under the barrier is wet and put a clean paper towel over it to absorb the wetness. Then look at the paper towel and see what color the liquid is that's been absorbed. It should be obvious if it's output or just your skin weeping. If it's your skin weeping and you're sure it's not output, then just keep doing the Domeboro soaks each time you change your barrier and change your barrier BEFORE it leaks. This will get your skin to heal. Don't sleep on your back... sleep in a recliner if you move around a lot and can't be sure you won't sleep on your back. I'd explain what you're doing to your ostomy nurse to keep her in the loop.
And... if you find there's no output under your ring, just clear wet weeping skin... ditch the Eakin ring and try someone else's. I tried the Eakin ring based on everyone's recommendations and my skin hated it. Made my skin itch and crawl after the first hour wearing it. Don't be afraid to experiment. You can get free samples from all the major vendors and your ostomy nurse should have a bunch as well.
Let us know how you're making out!
