Hi. My mom has had sores (on both sides of her tongue) since Jan 2017. Since then, she has had a lot of pain on her tongue/in her mouth, even eating anything crunchy or hard is too painful. She has been to 2 ENTs who tried nystatin (oral liq), nystatin and a corticosteroid mix (oral liq), and a 10 day course of prednisone that started with a high dose and then was downtitrated. the only one of these that offered relief was the higher doses of prednisone, but condition went back to painful at lower dose and case was not resolved. there was a brush biopsy that rules out malignancy. Neither ENT could dx the condition. She has been referred to a medical center in NYC, a specialist (Dr. Lawson), but he cancelled the apt and hasn't been able to reschedule for personal reasons. I'm wondering if I should take her to an immunologist in the meantime? I don't think its Becets, but wondering if a Mab might work given that prednisone did not. Thanks.
