I'm a 33 year old female. On Tuesday I went to see my mum who asked me what was wrong with my neck as it looked like it had a lump in it, I hadn't noticed it myself and could definitely feel something there when I checked. 

When I managed to get a GP appointment on Friday she said that my thyroid is swollen to around 3.7cm on the left side of my throat, in the middle of my throat there's also a large lump which measures 5.5cm. I had a baby around 4 months ago and had a tubal ligation during my c section, following this I've experienced night sweats, severe itchiness and hot flushes which I'd put down to my hormones, I also ended my pregnancy down around 1.5 stone from my first pregnancy appointment.

I know that these can be bad symptoms, especially with the lumps and my family has quite a bad history with both Hodgkin's and non Hodgkin's lymphoma. The GP has made an urgent referral to a head and neck specialist and I was told I would be seen within two weeks. 

I guess I'm just wondering if there is any chance my other symptoms may not be linked to the lump and could actually be down to hormones? Also what tests would a head and neck specialist actually do?

Any insight would be really appreciated. Thank you.
