Possible lymphoma which no one is taking seriously

Hello all,

how long did it take from going to the doctors to being diagnosed? I've finally been sent to the haematologist for possible lymphoma. I have 2 swellings in my arm pit that get bigger and small but never go. They have now settled but are huge. It's been  10 weeks they have been here for. When I saw the specialist they didn't seem bothered and wasn't sure they were lymph nodes (she thinks they are spots!) they are about the size of 20p and a £2 coin. She has sent me for a ct a week ago but haven't heard anything back. I have all the other symptoms other that itching. I'm just feeling a little frustrated. She said she "might" send me for a biopsy. Obviously this is really stressful and I'm struggling in understanding why whole process. 
just any words of advice or a chat with people with similar stories.
