I am 2 weeks post op, and i feel the same thing, mine is a pulling feeling, im ok when i lay in bed, but i started laying in a tanning bed and the hard no give surface aggrivates it, I am thinking that it is my port hanging up on my rib cage, that is exactly how it feels, cause i can push downward on my skin and where the port is located and it goes away, it is weird, my skin is still tender where the port is at, i hope it is ok, my cut from the surgery is healed nicely, thats not the prob. Im wondering if yours is the same feeling.
