Aw mama, joint pain and headaches a year after CS is something you should really check with your OB about, hindi na dapat ganyan normally, especially if it's affecting your daily life kasi may maraming possible reasons pa (nutritional deficiency, postpartum thyroid issues, muscle strain from lifting baby, etc.) and your doctor can properly figure it out. A few of us moms experienced joint aches in the first months post-partum pero nag-improve na after some time and once nag-start kami ulit ng exercise and proper rest, pero yours sounds like it needs professional checking na talaga. Don't wait pa, especially since you're already a year out, you deserve to feel normal again!
