Yes I have also suffered from this I am 1 1/2 years from treatments- I didn’t have the surgery so I still have my VC and larynx but my airway is so scared from radiation I may have a trachea always but I was swelling same as you are and I am using the lymph pump at home it is better for head and neck - but you may have to fight with insurance to get this but worth it, get the pump if you can.
