after tubal ligation ..

I had my tubes tied yesterday. I was given a big bottle of 800mg ibuprofen and oxycodone. but I was to loopy to even get directions they just sent me home. and I'm still breastfeeding an a lil concerned how this oxycodone is gonna affect me or my baby. I've avoided it till now didn't think I was in the amount of pain for that, been getting by on ibuprofen, but I have went all day and my body hurts! I figured id just take half of one. This is suppose to be a really good drug but will half affect my baby at all. since I'm still breastfeeding. I think I still got that gas running around inside me and its causing everything to hurt. my throat hurts I can't swallow, my neck hurts my back hurts my belly hurts I can't cough or nothing I can hardly bend over. anyone done the same.?
