Hello,
I just wanted post a follow-up to this since I've finally come through it all. After having a CT scan in the early stage of developing the lump, and two ultrasound biopsies in the following couple of months, it could not be definitively determined as to the nature of the lump. It was uncertain if it was a lymph node, a cyst, or something else. It could not be determined if it was malignant. As a result, a had surgery to perform an excisional biopsy. It turned out to be a benign cyst. With regard to covid, I want to restate that the cyst was not present (or at least not visible) prior to having covid. In my opinion, covid aggravated the cyst and caused it to either develop or increase in size to where it became now visible. Prior to covid, I had no visible evidence that a cyst was present.
