Swelling and dissolving stitches. How long does this take to rectify itself?

I had upper and lower lids done and developed chemosis which is causing my eye to droop slightly, look bloodshot and yellow. How long does this take to rectify itself? Im using antihistamine and warm compress but it isn't making much difference. Also how long does swelling take to reduce and for my dissolving stitches take to disappear. I have lumps and am concerned they will cause scaring.
