I've had a family member who has been very constipated lately and has been
going to bathroom a lot. After this particular family member used the
guest bathroom yesterday afternoon, the toilet clogged and started running
really slow - like it wanted to overflow. When I try to plunge the clog,
water started shooting out the sink drain, not the tub. The master
bathroom toilet started running really slow and overflowed and the shower
which is next to the masterbathroom toilet backed up, but it didn't back
up into the sink or the garden tub.

This morning the guest bathroom toilet acted normal, until I flushed the
masterbathroom toilet. And now the overflow, etc is starting all over
again.

Is is a clogged main sewer line, full septic tank (I have no idea where it
is on the propert), or a clogged in a drain line to the main sewer line
connection?
If you have a septic tank, it may be full or the leach field may be shot.
Best thing to do is locate it, have it pumped and then have a pro assess the
situation. If you are on city sewer, then your line is most likely plugged
somewhere.
