So the vein where I had my first catheter (which I requested to be removed and placed somewhere else because it was feeling uncomfortable) has now swollen. 2 weeks after being out of the hospital. It's now swollen and painful, a vein segment of about 5cm, exactly where the uncomfortable catheter was. It's most likely thrombophlebitis, that is a blood clot formed in that vein. It can detach and travel to the lungs where it can cause big issues.
So I got present #2 from the hospital, besides the chickenpox. We'll see tomorrow what's to be done about it.
I got from the hospital more problems than I came there with. I'm so angry.
