I have a question to those who had neck dissection prior to the radiation treatment.

It has been almost 12 months since my surgery and 10 months since radiation, but the tightness/stiffness of my neck still bothering me a lot. What made me worry is that the tightness did not decrease a bit, but rather intensified a lot. My neck is so hard that it feels like someone has stuck a piece of wood chip in there. Actually, it is more difficult to turn left/right or up/down NOW than 6 months ago.

I thought the tissue scaring process should be over long time ago. I do not know why my neck still gets harder and harder, sometime, I feel my throat is constricted too. My question is that: does anybody else have the same feeling ?
