Stoma appearance concerns. Worried.

For awhile now I've noticed a "dent" On one side of my stoma. It's slightly darker shade than the rest. Should I be concerned about this or is this normal? Could it just be oddly shapen?
Also, I've just recently changed my bag and I've noticed a really light, almost white spot on the bottom side of my stoma, close to my skin. Any idea what that may be? I'm worried.
I've also had very loose and occasionally green output for a little less than a month now I think. Not sure if that could be related to everything above...
Thanks.

I have all those exact same things! I have several white/clear spots an my stoma. Gi doc said no big deal.
Around the base of the stoma I think you can develop bumps from time to time because of your wafer and suture bumps if your still fresh out of surgery like myself.
The green stool is my primary color and these are all normal. Especially early on, but your output can be all sorts of colors and consistencys all the time. Important thing is that it's working and producing output!
Hope all that helps. My GI doc is the man! He really is a great doctor and wouldn't steer me wrong, if he says it's ok I believe him.

Thanks guys! That's really a relief.
