Alex,
My husband is 4 yrs post treatment this week and still suffers from the tingling and burning. The tingling comes and goes now. He just massages his neck and shoulders. The burning gets less and less.He found that avoiding spicy foods, cilantro, tomato products,and drinking milk with his meals helped.Now we can use seasoning again so it does get better. We had to make everything spice/seasoning free for a long time to help with the burning. He also has the forgetfullness and no chemo. We jokingly call it his mad cow disease. But we had his thyroid tested and found out the radiation had destroyed it, so he is on thyroid medication and it has helped. Hopefully this helps. Good luck
