Hi! I have a PICC line in place for receiving chemotherapy, and no trouble with it at all, but just curious about getting comfortable while sleeping at night. Any precautions? For example, can I lie on that arm or do I need to lie on my other side, so that the PICC is always up? Also, they mentioned not to lift my arm over my head....so just wondering what precautions I should take with it. Thanks so much for any advice.
