Hello, 

Let me start by saying I have not been diagnosed with any form of cancer at this time. I have very high concerns though that I feel are being brushed off by the last two general practioners I have seen about my concerns. Here's a little about me. I apologize in advance for my lack of brevity.

Four years ago I was diagnosed with Celiac disease and several food allergies. I went off everything they said I should not eat and I started feeling amazing. I went on with my life for three years feeling better than I ever had in my whole life. Then about 9 months ago I came down with an absolutely debiltating flu. I spent weeks in bed with swollen nodes showing in my thigh, neck, below my collar bone, under my arms and around my elbow. After about 2 months most of the lymph nodes went back to either not being felt at all or considerably less swollen. A small sort of figure eight feeling squishy lump remained in my neck, along with a lump about two fingers below my collar bone that is about the size of a walnut and fixed hard to my chest bone, there is also a small hard pea sized lump right below my jaw near my ear all localized to the right side of my body. I began experiencing difficulty breathing when I lay on my right side or on my back, when I bend over to pick something up and when I turn my head in that direction. I waited another four months to see the doctor. I figured with my history of inflammation and the fact that I had just had a terrible flu meant that these lymph nodes were simply inflammed. 

I started experiencing night sweats, interrupted sleep, uncontrollable itching in my legs every night. I'm barely able to get about 4 hours of sleep a night. I can't seem to eat without feeling like I've swallowed a watermelon no matter what it is or how little I eat. I've lost 43 lbs since my last doctor's visit which was about 1 year before this last vist with no change to my already limited diet and no additonal exercise. 

When I made an appointment with my doctor to express concern about the lump in my chest and neck and the difficult breathing, he zeroed in immediately on my asthma. He poked at the lump in question for a whopping two seconds and then ordered me a chest x-ray and blood work along with a new time released inhaler. Even after I contested that I am already on a daily inhaled steroid for my asthma. The x-ray did not appear to have any pooling of fluid around my lungs. 

I went and got all the blood work done. I haven't heard a word back from him at all. I am no doctor but I googled a few of my results and they are starting to worry me. If this is something besides my normal inflammation or residual swelling from a flu I feel like there should be a bit more expediecny. 

Everything I read seems to say that the presence of RBC Nucleated Blood Cells are a sign of trouble. What should I do? Should I wait to hear from him? Should I call? Should I seek a second opinion since he's ignoring my major complaint? Thank you in advance for any responses.
