Incision pain 3 months post-op, is this normal?

I had 300cc gel implants placed under the muscle in February. On my smaller side, I've had pulling-type pain/stinging at my incision pretty much since surgery. It almost feels like my incision is opening, although I know it's not. The pain usually only occurs at night with or without a bra, and usually when I change positions. my results are great and natural. Everything has settled. Just wondering if this is normal.. can't seem to find any other posts on it! thanks!
