Hi Denise, Swollen tongue
could be because of allergy (recall what she had the last night for dinner or any pill she took);
- anemia (severe), hypothyroidism
or certain tumors can cause tongue to be swollen.
If the blood is fresh, then, most probably is because of bruised tongue.
If the blood is "dark" and clotting-like, then, it has to do with gastrointestinal tract (varicose
vanes in the esophagus
All the best!
