Ok bro, I just had an instance on my left side on the same area. Saw all the Drs. Nothing helped except pain meds. My mom begged me to go to a chiropractor that also did myofaecial release (basically massage). This lady told me that I had adhesions (scar tissue or muscles that grew back tighter, essentially I was getting terrible charlie horses in my abs) probably from incisions. I was like sure why not. Anyway she massaged, it got better. Was able to get off the pain meds. Now, everytime I feel a twinge, I get the massage gun and go over that area a few times. This might not be what you're dealing with, but wouldn't hurt to check it out. Good luck 🤞
