Have you figured it out yet? I have the SAME exact thing!
Hello,
The blood under the skin which causes the discoloration of bruising should be totally reabsorbed by the body in three weeks or less. Since there is a lump under the adam’s apple also, I would like to rule out any enlarged lymph nodes or thyroglossal cyst.
To confirm the diagnosis I suggest you to get it evaluated from your doctor.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
