Thyroid abnormality ?

Hi everyone,

Hope your all feeling well, I have a question that I cannot find any answers to, so I thought I would try here

I have recently discovered a small lump on my thyroid. It’s tiny, millimetres big, and I had an ultrasound on my neck a couple months ago (that was for my lymph nodes, turns out I am recovering from an infection that’s taking ages to clear up), anyway, I wasn’t aware of this when I had my scan, but blood tests and everything have been taken and it’s all coming back normal. Everything is functioning normally, no major weight gain/loss etc. and I wanted to know what this is.

I have jaw pain randomly throughout the day, the front of my lower neck hurts from time to time, but the lump is not growing as far as I can tell. I have been trying to monitor it for a couple weeks and there are no noticeable changes in size and is located in the centre of my thyroid. It can be moved around but will return to its normal spot. It could be swollen glands as lymph nodes between my jaw and ears are swollen but I wanted to put it to you guys to see if anyone can provide any info.

I also have a vitamin b12 deficiency but am not vegan or vegetarian if that turns out to be useful info for anyone. Also, 18M with some distant family with thyroid function issues. If anyone has had a similar experience, it would be very nice to hear from you

Thanks for taking the time to read this if you see this, any responses would be greatly appreciated as this is worrying me somewhat. Stay safe everyone, hope all is well
