Hi MonicaJ,
YES, you can lose your ability to swallow! No matter what, you have to keep working at it even if it's painful. Many use Magic Mouthwash to help with mouth pain. It'll give you a window to help get food down. Eat soft foods.
Easy to Eat Foods I was given a list of swallowing exercises by my SLP and would be happy to post them. They're difficult as all get out but they help and work! You also must continue to do them well into your recovery as many have lost their ability to swallow years afterwards. I don't mean to make this scary but it is and it's serious business.
Positive thoughts and prayers
