Armpit Lump

Hi Everyone, 

Abit of background, went doctors last November with a lump in my armpit. Doctor said inflamed lymph node. I went back a week later for a 2nd opinion. Doctor said same thing nothing 2 worry about. I'd got a lot going on at work so thought maybe I was over reacting. Left in till February this year. Doctor said the same nothing 2 worry about. Went the doctors last week. He said it had definitely got bigger and would refer me. Next day had a phone call for an appointment today. 
Today's appointment consultant said she thought it was a blocked hair follicle, would do a scan but probaly nothing and I would need to go see my GP for antibiotics. Had the scan for them 2 then say I need a biopsy. This is where it gets difficult 2 explain please don't comment if your going to judge. I have a massive needle phobia. I didn't realise they would do a biopsy there and then. Completely freaked out. All rational thinking out the window. Couldn't calm myself down, got in2 a right state. I've watered some of this down but it was a nightmare. Consultant agreed that I was in not for state. Said they would send me for another appointment and use numbing cream but concerned because of how anxious I am they won't be able to go in deep enough. I know this is stupid but I'd rather be put to sleep, consultant said not an option. I get gassed to sleep before anyone says that's a needle.  
 

I feel so stupid walking away not letting them do it but I couldn't. Now I'm sat here thinking what if I have cancer it's been there 10 months and I just refused a biopsy because of a phobia. I'm not sure if I'm looking for advice, reassurance or just 2 rant about myself.
