My touch screen popped out a little and no longer works - is this a battery bulge issue ?
Could be. There is no way of telling from the information you have provided. There are also other reasons why the screen could have popped out such as the force placed on the backside of the phone when placing it in a tight pants pocket.
No one on the forums will be able to answer your question without examining your phone for a cause AND the required knowledge base to diagnose the problem.
