Post Lap Nissen Fundo - Pain at site

Hi everyone!
Looking for some advice from some experienced nurses.
I am a nursing student which is how I know about this board. I had a Lap Choly and Lap Nissen 3 weeks ago. I have just started developing a persistent pain at the site of the wrap. I first thought it was heartburn but I have had it so frequently now that I no longer think that is what it is. I never have it when I wake up in the morning but it starts in the afternoon and persists on and off for the rest of the day. I have not taken any meds for it yet. It does not matter what I eat or if I even eat at all. I still have it. Today I accidentally lifted the vacuum cleaner for a few seconds. That got me to thinking that I was also straining for a bowel movement all last week due to constipation from the Lortab. I have since taken some MOM and got some Metamucil which is helping a little. I did still have some trouble swallowing at lunch today so I guess that is a good sign it is still in place.

I see my surgeon next week but wanted to see what everyone thought.
Could I have possibly ruptured the sutures?
Has anyone seen this happen and what are the signs and symptoms?

Otherwise, what is this pain I am experiencing. Should I try some Tylenol?

Thanks.

Lisa
