4 months post Breast Reduction I have ingrown stitches, how can I take care of them?

So, I had a breast reduction 4 months ago and my "dis-solvable" stitches in the anchor line under the breast popped out through the skin. I have one or two that have become ingrown under some new skin, and these are quite painful. They are very sore, tiny bumps. How do i look after these? The ones that arent ingrown are quite long and scratchy. What should i do?
