I had mine fitted under general anaestetic, last September, and I love it. My hands are now free from bruises. As already said by Mejane and Lola, it will heal quickly. It sometimes dig into my when I sleep on my side; I just need to shift a bit and ai am OK.
Being able to swim and shower, really allow to have a more normal life. There is only one tiny drawback, whick I only found out after having it fitted. This is the fact that phlebotomist can't take blood from a portacath because they are not nurses. In my case it means a trip to the hospital if I want to get blood taken as none of the nurses are trained at my GP's surgery.
good luck with your treatment ladies.
