Can flatulence cause health problems?

My room now since it has been cold and I have been having some severe smelling biological type flatulence where it lingers and right now I have the fan on and ceiling fan trying to get the smell out of the room.

With the foods I have been eating I believe the gas chromatography are sulfur containing compounds such as
methane
hydrogen sulfide (rotten egg smell)
dimethyl

I have been having a headache for the last 3 nights, I want to know if this can cause any health problems from the expulsion through the rectum of a mixture of gases.
