I'm sorry you have had to go through so much. Every case is different. I underwent a radical neck dissection nearly 19 years ago after chemo and radiation. I'm surprised at how much more people are aware of the issue and what is involved. Back then, doctors' experience with it was very limited. As it turned out for me, the neck dissection may have been unnecessary as the other procedures continued to have an effect afterward. It wasn't fun, and there are definitely consequences. Any neck procedure runs the risk of damaging baroreceptors that control your BP, so you may already be at risk for that down the road. Most of the swelling issues went away, and though I look different due to the hollow spot in my neck, I don't give it a thought. It's a battle scar and I won. Should you decide to go through it, definitely seek therapy to address all the issues you will face. Hopefully, you have a support system at home to help you through it. Good luck to you.
