Hi, Had a lump in my for about 8 days in my armpit which is like the size of a marble and very knobbly (has been getting bigger). Saw the Doctor yesterday and he said he wasnt sure what its was.... said it was a lot of lumps clustered together, but didnt think it was anything to worry about. (so he says) But the booked me an urgent appointment for blood work in Friday. Do you think I should be concerned? Did the Doctor say its probably nothing to worry about, just to keep me from worrrying? (36 year old male)
