Is there an issue with my silicone gel implant post op 10 years?

I had silicone gel implants 10 years ago with no issues. More recently it looks like my left boob as drooped slightly however not that noticeable. But I have severe discomfort every month now with heavy sore feeling which is all round the left side and under and behind nipple. Feels like I am full of milk post pregnancy to describe pain and discomfort best way. I appreciate this is potential hormonal as appears more swollen an sore every month. However was never an issue before.
