Left side of neck for few days has been hurting and I think it's swollen the other side doesn't hurt and I have have weird feeling collarbone same side. I can't sleep or move my head cause the gland hurts. I don't have a sore throat or anything but I am achy. I'm going to dr Friday but I'm terrified why my gland is swollen and hurting afraid is some cancer that has spread. Been having collarbone pain too and itchy breast worried it's breast cancer and I also been having night sweats im worried it's lymphoma.Anyone know what could cause swollen gland does this sound bad
