Hi Riss I had radical neck dissection last year , cjf describes it pretty good I was in hospital for five days I needed to wait for the drainage to clear , they found a growth unexpected during the operation and had to remove it , so the operation was bigger , but it was not cancerous it was still confined in the lymph node which they removed, I was quite swollen and also had radiotherapy straight after , but I went back to work full time since Feb , the swelling has gone done a lot I massage my neck I bought one of those neck massage electric and I find this helps . Also the scarring is not bad as they keep it in the creases of your neck . Let me know if you need anymore information....
Hope your surgery goes well it's bit of a battle but worth the fight
