The surgeon took one look at it and told me that it is what is called thrombophlebitis. She assured me that it is most likely superficial which is actually a real thing. You can read about it here if you are so inclined. This is something that can happen after lymph node removal. Since it is superficial there is no need for blood thinners but I need to take Tylenol or ibuprofen and use cool or warm packs depending how it feels.
I have developed cording which is described in more detail when I looked up Axillary Web Syndrome. I had read about it after the surgery when I had these type of pains and when it felt like they had taken the lymph nodes out and inserted a rubber band along the armpit and inner arm all the way down to my wrist and then tightened it as tight as they could. I have gotten almost to full range on my right arm but there are times when the pain returns for a day or more.
I am happy that whatever is going on shouldn't affect my last round of the "bad stuff" coming up on Tuesday. We certainly don't want to drag this out any longer than we have to! There is also a little confession I have to make. I posted this nice and restful looking picture of me but I haven't been very restful. I have had FUN but I haven't been sleeping as well. Time to slow down for a few days.
