Why do nipples hurt after wearing compression garment for 12+ hours?

Hi I had gynecomastia and also Vaser lipo for love handles. I have been wearing compression garments for 2 weeks. The bruises are mostly gone and swelling is getting better. I feel more discomfort, pain after wearing compression for 12+ hours, especially the nipples seem to get hard and hurt. Even the waist hurts after sitting. Is it normal for the compression related discomfort to increase after 2 weeks and is it okay to temporarily remove compression for 3 to 12 hours if discomfort is there?
