So sorry you're having this problem!
I have the problem with the scarring/adhesions & it has been worse at TOM the last few months. I asked my MD & he thinks it's because of the swelling/bloating in the abdominal area putting pressure up against the muscle the port is stitched into.
A week or two ago I went off the BC pill (already had tubes tied & was just taking it for cramps/headaches) because the bloating was just crazy. We'll see in about two weeks if the port pain is any better this month.
Take care,
Amy
