Found "lumps" in my neck :(
You don't have a tumor for God's sake! If this happened post infusion you've got iron infusion lymphadenopathy. It happens to a small portion of recipients and causing the exact symptoms you describe.
BACK AWAY FROM GOOGLE NOW.....THAT'S IT BACK UP..........
Right now that you have another diagnosis aside from NHL go and see your GP and request a biopsy so that you can put the whole "I obviously have cancer "thing behind you, I hope that I'm right and that you don't have to ever face the prospect of going through treatment for such a ****ty thing.
Best of luck.

I've been through this scare as well and finally after multiple tests, ultrasounds, and biopsies I will be having surgery for a total thyroidectomy August 3rd. I was diagnosed pre-DS with hashimotos thyroid disease. The "lump" is so large in my neck you can see it just looking at me. I have several nodules, but the most dominate one is 6cm in diameter. I've lived with this for a long time. The only reason why I am getting the thyroidectomy at this point is due to it's size.
Good luck and do not worry yourself sic****il you have a reason and proper diagnosis.

When I first noticed my "lump" my thyroid labs were normal, but within 2 months they were abnormal, of course by that time my first ultrasound and biopsy was done. My endocrinologist explained to me that even when people have thyroid goiters or nodules they will often have normal labs until you become hypo or hyper depending on the reason your body responded. For example hashimotos or graves disease among many others.
Best of luck to you I hope all goes well!
