Last year I was hospitalized with sepsis, as a result I had a picc line from December 2009 through mid Feb, 2010. After the second (abdominal abscess) relapse the picc line was reinserted for approximately 3 weeks in late May. I now have an extreme sensitivity to heat and cold in the vein that runs up the inside my left arm (site of the picc line) and around my armpit. It also is irritated if I lift something heavy. Even on a good day, when it doesn’t hurt, I can feel it, and would describe it as irritating on a bad day the pain ranges to about 7 or 8 on the pain scale. Please don’t tell me to use a heating pad or cold compress, this does not work and only makes the matters worse. What could be causing this? What can I do to alleviate the pain?
