Hi Newbie
Everyone has trouble in the first few weeks, your problem is nothing new.
There are several ways to stop the irritation around your stoma.
Get yourself some 3m no sting barrier spray, comes in wipes as well.

Also use a barrier ring/seal, I use the spray above with a barrier ring seal.
Convex bags will help you get a better seal and a elastic belt from supplier.
Go to the chemist and get some 3m micropore tape, someone here recently revealed they put tape straight over the irritated skin then apply the bag as normal, cheap , fast , quick fix and gives the skin opportunity to heal.
Get in to see the stoma nurse straight away, there is no need for you to suffer.
All of the above should be available at the stoma nurse amongst other solutions.
You will get a handle on this soon everybody does before too long.
Good luck
