question: I have had some weird symtoms over the last 6 months and I'm not sure if they are related or what they mean. I have a few swollen lymph nodes on the left side of my neck that seem to change in size every few weeks (grow and then shrink) but always remain at least the size of a marble. Also in the hallow of my neck by my collar bone I noticed a very hard, alsmost bone like, lump. It appeared out of nowhere and seems to have stayed the same size (about 2-3 inches long). I'm also experiencing this annoying pulsating sensation below my heart. I had the doctor check my lymph nodes, but she said they were nothing and that was it. Should I be concerned? I've also had a sore throat on and off for about 1 month
