[|Human|] My Mom had a couple canker sores on her tongue that have now gotten better.  However, over the past couple months her speech has become hard to understand.  In touching her tongue it feels stiff and has a hard, lumpy feel to it.  When asked to move her tongue, she cannot move it side to side.
[|AI|]  Hello, There may be a healing period where the texture of the tongue feels different. It is common to bite the tongue as well. This can feel bulky.  This difficulty should not last over months. I am concerned if there is swelling with speech affected that a more serious condition present. Limited movement is a concern especially if becoming more restricted. Was the sore tongue seen and diagnosed by a dentist? Please consult a dentist for an exam. Repeat episodes of ulcerated areas do occur especially if viral. Allergic reactions can occur as well. It is recommended to have a clinical exam to get the most accurate diagnosis. Thank you for your inquiry.
