Thought I would let you know how I got on at the breast clinic, after having so many kind messages on my previous thread.
It was a harrowing couple of hours at the hospital this morning, but the good news is that all is well.
The mammogram that was done 2 weeks ago showed an area of concern, which is why I was called back. They did a layered image at different depths, full physical exam and ultra sound. Nothing showed up, so I have the all clear. They showed me the scans and talked me through the ultrasound, so that I could see for myself.
I told them about the breast pains that the locum GP hadn't been very helpful. I was told again that breast pain is very unusual as an indicator for cancer and usually only shows up once there are already visible signs. Really lovely nurses and doctor, so kind, and they listened to what I had to say. We did talk about the PMR and the pred, and the doctor told me that the kind of pains that I was describing aren't usually a sign of anything going on in the breast. I said that it was hard to tell if it was in the breast or the chest wall and she thought that, given that their checks were good, that either referred pain or something PMR related was responsible. I do remember a physio a long time ago telling me that problems in the upper spine can cause pain in the breast, so that seems to match up. Though they did say that if anything changed or if I was worried at all, I should ask my doc to refer me back to the clinic.
Anyway, they have put my mind at rest for now. Something less to worry about. My upper back around the trapezoid muscles is very tight, so it does seem like it might be PMR related.
Thanks for the support on the earlier thread. I live alone and don't go out much since I have been ill, so no-one else to talk to. I was trying to stay calm, but you know how difficult that can be, at times.
