I had endone,panadol and voltaren until day 3, then panadol and voltaren probably twice a day for at least a week, possibly longer......I found the voltaren helped. Interestingly though i recently hurt my shoulder and went to get voltaren and 1 chemist lost her sh*t and said I was giving my baby stomach ulcers, and a different chemist said not under any circumstances should you take it while bfing and she wouldn't give me any!!!! And this was for a 5mth old not a newborn! Meanwhile the anethetist is the one who prescribed it, I heard him tell the nurse when leaving theater.....very confusing, but I didn't take it....
Hope you get some rest, try not to overdo it. Enjoy those newborn snuggles!! x
