Hello, I'm 36 years old and a month ago started having stomach problems, nausea, dizziness, low night fevers..etc., I figured I had a stomach bug but at the same time began to feel pain under my armpit that spread to the breast area closest to the armpit. I asked my doctor about this pain, he said, he felt no lumps and that it was probably my lymph nodes bothering me as a result of the stomach bug and that it would go away soon. My dizziness got so bad I went to the ER one night and also complained to the ER doctor about the breast pain but he said he felt no lumps and told me not to worry about it. It's been a month, I am feeling a little better from my stomach although I still get dizzy after I eat and wake up nauseaus from time to time but the pain under my arm and breast is still there. I'm terrified, I saw another doctor and he's sending me for an ultrasound. What could be causing this pain for so long? One doctor said it could be my Lymph Nodes, the other said he wasn't sure, and the other one said it wasn't my lymph nodes! what can this be?
