I have a bubblie stomach with rotten egg burps

I'm not sure... but I used to have that problem all of the time, your post just made me remember that I have not had them since my gall bladder was removed a year ago this Jan.I had severe cases of indigestion and finally late in the year I started to have a lot of pain that continued to increase in frequency and severity, until it was pretty clear it was my gall bladder an ER visit and a ultra sound confirmed it.
My son also used to have them but he had bleeding ulcers from chemo drugs and predisone just to name a few things he was taking.
My guess is it is probably a reslut of a underlying condition. If it is real bad or has continued over a long period it may be time for a doctor visit.

I have to agree with Bushg here. It is most likely an underlying problem. Could be anything from H. Pylori to gall bladder. Best have it checked out by your health care provider.
