Girls, I don't even know what to do anymore. I have anal fissure, they prescribed me treatment for 14 days, but it's not compatible with breastfeeding... I've been suffering for over a month now, without treatment because I'm afraid to separate from the breast for such a long time, I thought it would go away on its own, but it's getting worse, pain is already developing weakness, and emotionally it's hard, like I'm giving birth with a rupture every day. What would you do in my place? What mixtures are better to give? Is there any chance that I can resume breastfeeding after this?
