I saw my doctor yesterday after 6 weeks of a painful lump in my armpit, night sweats, fatigue with no obvious illness. 
she had a feel and said she doesn’t know what it is, she can feel it’s rubbery and lumpy. I’ve had bloods done today and I’m being referred to ultrasound urgently. I said I was worried about it being cancer and she said we will have to see what the ultrasound shows but a biopsy is the next step if it shows something other than a cyst. 
I’m not sure what I’m saying or asking, has anyone had similar? Is it true if there’s pain then it’s not cancer? I’m really worried about this.
