So, it's interesting to read this and relate to some of my symptoms, even though I did not have RT, only a neck dissection. My neck, especially on the left side (where the dissection was done) feels very stiff and aches at times, although I try to do my stretching exercises regularly, In addition, I get the worst cramps under my chin especially when I've done a lot of physical exercise or am tired. And occasionally, I get a very weird shooting pain up the back of my head - not as often but I sure know it when it happens! I put it all down to both scar tissue and nerve damage from the ND... Have asked my docs about it but they have no other suggestions to help besides what I'm already doing. But I agree, it's a small price to pay if I remaing healthy and cancer free!
