I ended up with something like that after DD2. I tore in the oppisite direction though, so I had no idea til she was over 12 months old.
Mine was towards the front (quite an odd spot if you ask me!) & thankfully was far enough forwards that I didn't feel it. Have no idea if its still there since DS though
I'm not sure if you're better off waiting til its healed properly or not? They might be able to fix it?
