It kind of sounds like maybe her medicines are making her stomach feel bad. Especially since she has had *N for a little bit. People can have *D for many reasons too. Just keep your hands washed and clean the area around here with what you can. If you can't spray Lysol can you wipe things down with clorox? These are just suggestions as a precaution. I think you will be ok. I hope your mom feels better soon also. Hang in there.
