What causes a lump on the neck along with fatigue and dizziness?
Patient: My english is not my native language, but I ll try to explain. Female 27. I got this weird long lump on my neck in the right side, it pulses and seems it have grown. I feel tierd all the time and I have noticed few days ago my pupils are not the same size. I feel also weak for some reazon, I am usually strong women, but even carrying groseries from store is hard. Stepping up the stairs is exausting. Dizzyness and light headed. I got chekt by doctor, but he could not say whats wrong. He saw my pupils are little diffrent, but reacts to light fine. He seemed not to take me seriously. Also im anxious about my health Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  The lump on the neck mandates possible lymph node enlargement or others. The fatigue and dizziness narrate low hemoglobin, deficiency of vitamins, or other elements. I recommend to consult in follow up with a photo picture of the lump as an attachment for best possible evaluation.  Hope I have answered your query. Let me know if I can assist you further.
