Aches in ribs and gastro pains post herceptin

[MCS]

Just curious for the ladies off Herceptin.

since I went off Herceptin in december, I've been having these strange gastro pains that almost feel like spasms or contractions. These only occur at night when I sit down after dinner- usually 1 hour after dinner. Once I lie down or sometimes take an ativan, they feel better or go away entirely . They don't occur after breakfast or lunch. they don't feel like gas pain.

I've been also having side rib pains, only on the lowest rib on the left side. the original dx was on the right breast. It feels tender to the touch, like a bruise. It also hurts when I sit for a long time, like right now. I had these even during herceptin (i did read prior threads).

my ct in sept did not show anything.

has anyone experienced this? I'm a little scared as to what could be wrong. is it muscle tissue or bone? distant bc, ovarian cancer? Our minds do wander. I looked at the thread of herceptin side effects but this is happening after herceptin.

any weaning off effects with herceptin?

Thank you
