I get a flash headache in the back center of my head when I swallow too much or too fast. It goes away fairly quickly though. It's odd and I couldn't find any information on it. Anyone else experience this?

Goodness I'm sorry you're experiencing that. I haven't experienced that but I had flash abdominal pain into my back when I got full. I hope you get some answers. Did you ask your surgeon?

I actually do experience that same back pain simultaneously. I've heard this is common with the lap band because they think it punches a nerve. Don't know what could cause this with the sleeve.

No idea, but mine has since gone away. I'm just over 4 months out.

I had that in my shoulder for the first month. I think it's referred pain.
