Does anyone have enlarged lymph nodes in their neck from Long Covid?

Since starting this nightmare in early 2020, I have had this large ‘lump’ sitting over my carotid artery on the left side of my neck. When I first noticed, I showed it to my neurologist at an appointment thinking it was a lymph node. He said, I can see your heart beat through the ‘lump’ and he showed visible signs of concern and immediately sent me for MRI of my carotid arteries. That was all fine, thank goodness. From there I was sent to a vascular Doc for ultrasound, CT scan etc… all results came back normal.
Today at a physical with the nurse practitioner at my PC office, I mentioned that it is still very much present. Now, 2 years later, they are super concerned that it is an enlarged lymph node and are sending me for further diagnostics. I feel like this should have been explored when I first mentioned it. 🤷‍♀️. Does anyone else have this symptom?
So of course now I’ve got one more worry.
