Aw Ali that’s awful for you. I know exactly how you feel. I’ve had breast and underarm pain since January 22 and had two clear mammograms and part ultrasound last year. No cause identified for the pain but it’s relentless. I’m now awaiting my third appointment and told today that it will be at least another few weeks before I get a date. 
Totally understand your fears as in the very same but it sounds like you could have another cyst? Our minds take us to very dark places when we are so worried so keep busy as everyone says. Not easy I know but time will soon pass and by this time next week you will know for certain what’s going on x here to chat anytime. 

Hi Pauline, thanks for replying :)

it’s nice to know that we’re not alone, I find the waiting the worst! You’re so right about going to dark places, sometime the things I think are terrible and I can’t stop spiralling.

I hope all goes well for your next appt. I once had bad pain under my arm, that spread down the side, when I had an ultrasound they found that one of my lymph nodes was just close to surface and it can cause pain, I’m sure with your clear mammograms and ultrasound it wouldn’t be anything sinister but better to be on the safe side.
