My question is I have noticed swollen hard fixed Lymph nodes in my neck for a while now the first one was two years ago and Ive been to my dr numerous of times to ask her about them and she just said its a nasel drip or maybe im getting over a cold and so on, well she is finally taking me serious since there still swollen (just larger now), hard and fixed, they took a while to get larger but the swelling has never went down even a little, she ordered a complete blood count and that was negative, chest xray negative, gall bladder ultrasound negative, and did a blood test to check my liver and that was negative, I went back to a CT scan with IV contrast and the test results came back as multiple non specific lymphnodes and I am curious as to what this means and what it might be, I go and see a ENT dr next week but I just have some questions now :-) I also seem to be tired, adominal pain, chest pains in my upper left side, i seem to have alot of bone aches and real bad trolly horses in my lower legs especially at night, at times I get confused, its hard to breath at times also. My neck is very stiff and I am always hoarse, and my throat feels tight at times.
A few years ago I also had a MRI of my brain done because of bad headaches and it showed that in my front lobes there was dark areas, but I was never able to follow up on the neoro Dr due to another family member being ill
Thanks for your help in advance :-)
