Go to doctors or no?

So my little one is almost 8 months old about a month ago she was struggling to poop, I could tell she was in pain she would do a screeching cry and pull her legs up it was horrible. I took her to the doctors and I was correct she was extremely backed up the poop that was in her diaper was poop that was pushed out because there was no room for it to stay in pretty much. They prescribed me medicine for her to help to get it all to pass. Well we did that. It worked she was back to my little happy girl pooping fine as could be eating great everything. Well come this past week that has changed. She will cry for an hour multiple times throughout the day to where nothing I do will help. She will refuse her bottles and scream if I show it to her. Her poop in the past two days has become more solid not hard balls though. But I’ve noticed when she is laying dow or in her high chair she will start to squirm or arch her back and then become upset. Me being me I’m instantly concerned something is wrong she’s my first baby. I’m not sure if it’s something with her stomach again or just a cranky phase that nothing pleases her. I feel like a crazy mom because I’m always worried. She does drink water throughout the day sometime I’ll put half an oz of juice in it Incase her belly is backed up. I watch what purées I give her and see how she poop with them. I don’t do cereal as thy did cause hard poops. I probably will make another appointment to be on the safe side but has anyone else gone through this? Any tips?
