I will tell you this. My veins are great. All the nurses love them. They are like road maps. But even with that, the doctor told me that the veins can still blow after being stuck so many times. Now, I am very skinny, I hate the port, but.... tis better than a chance on blowing vien. My Doc also said, that if the IV is not in right, the chemo meds could leak onto the skin and burn. I was not wanting the port, but after hearing all he had to say, I was talked into it. It has advantages for sure. Just because I am skinny, I feel it all the time. THAT is what I do not like.
