Yeah. I use a cuisinart but I just use it for smoothies. I agree with Maria. Maybe talk to your drs. A therapist may help with the eating and swallowing. Did you have a full glossectomy? It sounds like you did. This would make eating anything other than liquids quite hard but there are others here who have managed. I usually use something like almond milk or water to get my food down if its dry or harder to swallow. The damage done through radiation is long term - it requires long term work on stretching and physio to maintain any sort of range of motion - As far as I can tell muscle memory is damaged by radiation but after a long period of time you will begin to make gains (once the original cells effected are gone or have had a chance to repair. The average life span of a muscle cell is 25 years (although some can last a life time) a bone cell can last as long as well though the average is 15-20 years. This is why radiation has such far reaching consequences. Normally with muscles the use it or lose it idea is very accurate. With radiated areas - its even more prevalent.

yawning, stretching helps.

Im always opening my mouth as far as I can, exercising my tongue. Swallowing.

hugs and congrats on getting through it.
