<human>: Yes , I been dizzy  for over fine days now and I just notice a knot on my artery of the neck.  I notice a little of a cough and blurry eye sight. I  went to hospital emergency had chest e-rays, eye checked and blood work not abnormal.  What could be wrong?  P.S.  I didnt notice  the neck until today.
<bot>: Welcome to Chat Doctor. 1. The possible cause win this case could be lymph nodal enlargement, and vascular pathology in next place.2. Lymph nodal enlargement can be seen in infection/inflammation/malignancy anywhere in the body.3. In any case I would recumbent to get an ultrasound examination done.4. Ultrasiound will exactly tell where the lump is taking up from, nature of the lump and its extensions, also if vascular - which vessel is involved. 5. In case of mass lesion - an FNAC - fine needle aspiration cytology to assess the nature of the lump. Good luck Hope I have answered your query.Anything to ask do not hesitatehttp://doctor.
