[|Human|] My friend experienced a swollen tongue as she was in bed, she felt like she was being choked. It went away when she sat up. She has blood clot in right thigh and has been on warfarin for as least 6 months. She stresses out easily and has her mother on hospice in her home and she is the caretaker. Nurses and other helpers do come in home occasionally.
[|AI|]  Hi. Thanks for the query. Swelling of tongue that happens suddenly is commonly due to Allergic reaction. Allergy can be due to common causes like any foods or medication, any big bite, environmental pollutants, animal dancers etc. So my suggestion is that if the swelling is severe and causing breathing difficulty she should immediately consult an Emergency room and get evaluated. Anti-allergic medication like Levocetrizine, Allegra etc. can be advised along with a steroid shot. A blood test can be done to confirm the exact cause of the swelling. Hope this helps. Regards.
