Hey Kate,
I had under the muscle and didn’t have any codeine, I just had ibuprofen a few times. And under the muscle is supposed to be more painful they say. I do have a good pain threshold though. Haha makes it sound like I’m bragging. I promise I’m not, just thought it might be reassuring to you. 😊 I know everyone is different. But honestly, I know it’s hard not to panic, but the pain for me was more when I moved or used my upper muscles. Majority of the time it’s just tightness and discomfort, but all really manageable! It’s all worth it in the end and I bet you’re tougher than you think! 😀 best of luck with your op!! Xxx
