About 2 and a half weeks ago I felt an achy pain under my right armpit, a few days after the pain begain I decided to feel around and found a new, quite large, square flat lump. I mention the square feeling lump because I can't find anything online about anybody else feeling a lump of this shape. The lump / surrounding area was tender, I can move the lump though, I rang the doctors and got an appointment 2 days after. The doctor didn't seem too concerned but did do a really thorough check and sent a referral to the hospital for an ultrasound.
I still haven't had my appointment for the ultrasound, to be honest this has ruined Christmas for me and I have spent almost every day crying and it's affecting my relationship because I am so stressed every day and don't have many people to turn to. 2 days ago I went for a private scan to try and elieviate my worries but was made to feel quite stupid and was told the lump was due to shaving or a swollen lymph node? I get shaving lumps every now and then but NEVER has it felt anything like the lump that's been under my armpit for 2 and a half weeks, and usually is more like a squeezey spot sort of thing. I haven't been ill or had any infections recently so I am struggling to understand why I would have such a massively inflamed lymph node for no reason for over 2 weeks now. The dr who did the private ultrasound said that the only thing she saw on the scan was a 0.4mm lymph node that wasn't anything to worry about, the lump I can feel is most definitely at least a 1cm if not more. Is it possible it wouldn't have shown up on the scan? Is a lump different to a lymph node ? To add to this I now have a new lump under my opposite armpit which hurts just like the original one. The pain in the original lump has now completely gone but the lump is still there.
I am young, 22, I understand that it's not as common for lumps to be sinister at this age but I am starting to become seriously emotionally unwell because of the anxiety and stress waiting around for appointments is causing me. I rang my doctors today just to be made to feel like my concern wasn't worth it, even to the point that my doctor told me I needed to cancel my appointment if the lump went away, I'm 100% certain the lump isn't going to go away and I am absolutely terrified.
I'm not sure if I wrote this for advice or just for an outlet to somebody other than my boyfriend. I just don't know what to do , I don't know if I should be worried or if this is common. I just know I'm really struggling to cope.
