Has anyone experienced sharp pain right below the J tube?

I had my j tube put in August 4th, I was able to start eating again about a month ago and now getting pain, typically after meals below my tube. Sometimes the pain is excruciating but only when I move, if I stay still it subsides.
Drs are a bit stumped and Im just now having them sort it out, was hoping someone might have had the same situation and identified the cause/solution.
Thanks,
Travis
