Don't ignore pain in the lower right stomach area, could be appendix. Even us old farts have appendix issues, always thought it was a younger kid problem.
Tuesday my wife had pain like above, dry heaves, felt lousy overall all day. At 4:00 we took her to emergency room on her doctors advice. After running some test, etc, they took her appendix out. Anyone that knows my wife, knows she's in super health and condition, so it can happen to anyone.
Home now and doing great, can still be be a serious condition and very common, but it's a quick, easy fix these days.
