Oh Laure' I wish I had some super advice to make it better, but I don't. I only had one and had it removed 5 days after surgery. But I only had a partial so I'm sure that had something to do with it. I found that the suction is what caused the pain. And that is what gets the fluid out so it's a good thing, even though it hurts like h*!!
Are you wearing loose clothes to keep it from rubbing against your skin? I could only wear jammies during those days. And I used the less sticky medical tape to tape the tube to my tummy in a way that it wouldn't kink but it had some slack so as not to pull at the site.
It's going to feel SO good to get them out. But in the meantime you are in my thoughts and prayers for a speedy recovery!
Love and hugs,
PS. Are you right handed? Maybe the use of that hand is making it more painful. Try to limit what you do. I know it's hard but it may help.
