I noticed it the other day whilst changing my cup. I called for an appointment on Friday but due to the wait the receptionist decided it was best to triage me. I was seen really early Saturday morning. GP said she couldn't see anything there but when she felt there's obviously something there and it's tender. she's got me an urgent referral to the hospital.
now I'm stressing because I don't know what it is or what to expect 
I'm on 6 monthly recall at the moment which doesn't help my stress and the GP said she doesn't want me done until the hospital say so, even though I'm overdue because of not long having a baby.
it's back and right, about the size of a finger, hurts to touch (which includes sitting) and not a cyst, absess or birth trauma. anyone relate?
