I hope you get some good news about the test results and can ditch the IV lines.It is nice to be off the antibiotics, however temporarily, so the GI and itching skin issues can subside. PICC lines are definitely the tool of the devil.
Good luck. Really feel for you and hoping for the best.I can go on oral antibiotics and get the PICC line out, I can start working out and doing yardwork, and generally have a life again. If the infection is not under control, I may have to continue on IV antibiotics, and have some tough decisions to make.
