Have you had a consult with a speech therapist? I was given guidance and exercises to help maintain swallowing function during and after treatment. If you are not able to see one, I recommend searching online for exercises to help dysphagia and do them 2-3 times a day. They consist of tongue exercises and things like swallowing with your mouth closed and tongue on roof of mouth. If you can see s speech pathologist do so ASAP as you already started treatment. Hope this helps.
