I recently noticed a lump in my neck, was very sore and tender to touch. I went to the doctor and after a quick examination she said that she it looks like it might be a thyroid problem but i was to come back in for bloods and a scan. I am not due back to the doctor untill next week, however i was feeling my neck. As i have been frequently doing now to check if its still there, and i cant feel it anymore. Is it possible its gone away?? Should i still follow up with my appointment for bloodwork? I am 24 and i have bad problems with my weight. I am currently a size 14 and probably weigh around 12st. I have done a bit of reasearch on underactive thyroids and it would very much make sense if that was the case. But i dont know if ive now made a mountain out of a molehill?
