hello i'm hoping someone can provide stories on something similar they've had or just help me know what to expect. 

went to gp two months ago with multiple lymph nodes behind my ear. they gave me antibiotics to see if they would go down. 

went back yesterday as they haven't gone down and i've also developed two in my groin. with intense night sweats every night. 

they took a urine sample yesterday and said they will organise urgent referral. i've suddenly got a haematology consultant appointment TOMORROW (2days after GP visit) which is extremely quick and a little concerning to me. it's at a cancer centre. but the results of my urine test are not yet back and my blood test is later on today. 

i think they are concerned about lymphoma/myeloma. 

what should i expect at this haematology appointment? i'm only 19 and it's on christmas eve, i'm so anxious. 

many advice or help is appreciated x
