I had much the same problem!  Veins was breaking having the cannula really painful,  so i had a picc line inserted.  I had it done at radiology dept.  Aneathestised all around the area.  It was sore n swollen n bruised for a week but other then it being a bit to high up my arm it heals n you cant really feel it there.  Its cleaned n flushed weekly at the hospital n everything goes into or comes out of your picc.  Much easier then having all the bloods n chemo going through cannulas each time.  

Thank you for your helpful response

Hi, I had a PICC line inserted for my chemo.  It didn’t hurt at all - I could barely feel anything as it was inserted, and it made chemo infusions much quicker and simpler because the tube was simply plugged in.  It didn’t restrict movement or what I could do with my arm though I did have to wear a waterproof sleeve in the shower.  I ordered some colourful stretchy cotton PICC line covers online because the cover the hospital gave me was a bit uncomfortable, plus they had the advantage of not looking “medical”.  Another positive is that I wasn’t forever covered in bruises due to the nurses trying to insert a cannula! Best of luck 

Hi, I had a Picc line done ust a couple of weeks ago, I didn't feel a thing, all done very professionally, doesn't really stop you from doing anything, gets cleaned once a week by district nurse and also by hospital when receiving chemo. Just have to keep it dry when cleaning yourself up, but you get covers from the hospital or district nurse. Good luck, you'll be fine, you can do this.
