I Have Had 2 Lymph Nodes For About 8 Months.

I have had 2 lymph nodes for about 8 months. One on each ear. My nose is swollen and hard to breath with. Not to mention I have had awful mucus in my lungs which makes it harder to breath. I also have bad constipation get ugly headaches. Sometimes feel a stabbing pain like pin and needles on my back. I don't know if this is related to thyroid cancer. Can someone help me???
