For about 3-4 months now ive had a swollen lymph node/s above my coller bone. ive visted the doctor(3-4 months ago when i noticed it) the first time it showed up he got me to take an ultrasound(never heard anything back), just today i went again for the same reason swollen lymph nodes and problems breathing (i smoke a lot) he than told me it should just "go away in a few months".to get an idea of problems im having-Night sweats (nurse said i have a slight fever 99.4)-shortness of breath-wheezing-neck pain (i want to say it starts from where these lumps are its like a headache type feeling.)-stomache issues/pain (Ive been vomiting on and off for no reason, he prescribed anti acid meds which to me did nothing)these lymph nodes or lumps ARE hard and are not tender to the touch. when i "move" it it seems to push against my esophagus and make a crunching noise. i say move because it goes back to the original position of course. im on here to ask if i should maybe go to the walk in clinic and see what happens there?
