I feel your pain, Michelle. I think you should give it some more time though. I retore around 4-5 weeks after LIS too. In theory, the muscle should be looser now and any tears you get should hear faster and with less pain.
I'm 6 months after LIS now and still tearing. It totally sucks because I can tell my muscle tightened up again, but the good thing is I don't have as much pain with these new tears as I did before surgery.
Still, I know what you mean about starting to feel hopeful and then getting crushed again. I'm right there with you. Just know your not alone in this...it's not just physically painful and draining, it's an emotionally difficult thing to go through. I certainly cried after this most recent retear.
I don't even want to tell my husband I'm having issues again, I know I put him through hell the last time and he's going to push me to just get another surgery ASAP so we don't go through it all again. I'll tell him when I'm ready, and I'll go back to the surgeon when I'm ready too.
The only thing you can do right now is wait and see, and take some Miralax/Movicol if you're not already. There have been some people on here who retore and went on to heal perfectly without needing another surgery.....and then there are others who need another surgery. It's going to be impossible to know which way you fall until more time passes. I'd say, in 6-12 months if you're still struggling, it's time to see the surgeon again. But until you know more, try not to stress out. This isn't your fault and you are doing everything you can to heal from this. Sometimes sh** just happens.
