I have crohn's disease and am immunocompromised by medication to treat it.
Recently I noticed a lump on my neck. It's hard and wont move. It has been there for a month ish...the last few days I think it is getting slightly bigger and ive noticed some swelling (I've circled both locations on the attached picture)
The lump is painless but I occasionally feel a slight ache in my shoulder (may be unrelated)
My doc referred me to ENT rapid clinic and the ENT referred for an ultrasound. He said probably lipoma but my lump is hard and wont move, whereas I've read that lipoma are easily moved.
At the ultrasound what will happen, will it show if its anything sinister that day? Will they know straight away. I'm worrying myself silly about it.
