Oh wow Sue, sorry to hear all that. I have a slightly different story. Diagnosed with bc in late May, with positive lymph nodes. All other scans etc clear. Having chemo to start with. Port inserted 19/6, started chemo 23/6. Saw oncologist again on 6/7, and mentioned what I thought was a painful swollen node in my neck on the opposite side. Off I was sent for another U/S & FNA. Had that done on the Friday afternoon, discovered a clot in " a superficial tributary" of the superior vena cava. Talked with GP late that arvo, on oral thinners. Went to the hospital on the Monday to get port checked before chemo on the Tuesday. The registrar spoke with the Oncolgist, the result? At this stage, a month on clexane twice a day. I see the onc again on 4/8, and will find out then from him where to next, and what it all means for me. However, I hadn't associated until your post, that there might be a link between that and the slight breathlessness that I get when standing, although not so much when walking.
Injecting cleaxane, horrible isn't it? Hope you're doing ok
