I am 8 days post op and have a strange pain in my back. It is located dead center and feels a bit like when you get a brain freeze and it goes into your back. My back has also been tired, but this pain is a little different. I can feel it more when I inhale. I have no heartburn (GERD) symptoms at all. Pretty much pain free, except a little tender at incisions. Pain level for my back is 1-3, but fairly constant. I had it on the 3rd day after surgery and then it left until yesterday. Any ideas?

Sounds muscular to me, but obvs I am just making a wild guess, but post-surgery it is normal for backs to be a bit niggly. I had a similar issue and couldn't take a deep breath and it just got worse until my whole back was in a spasm so I had to get a dr to come to my house and had a week of diazepam until the muscles all relaxed again.

Give it a couple more days then go get it checked out if it is still bothering you. Hopefully, it is just a knot causing some small spasms- which can definitely be constant. Hope it goes soon
