Hi Andy. I didn't have surgery but had radiation and chemo around the same time as your surgery (late 2019). I did a barium swallowing test (that GM Craft mentioned above) with the speech therapist about 3 weeks ago. I found it quite helpful to watch on the screen how foods of varying consistency were going down, where they were meeting resistance and how to move my throat muscles better to get it moving. The therapist also gave me exercises to build the muscle groups that had been weakened during treatment. I would suggest it.
