It's been a little over three months and my port area today seems warmer than the rest of my stomach. This area has been a little bit tender since the surgery. I can't go to my dr because he is in Mexico. I'm very paranoid about this. Has this happened to anyone else?

infection kind of warmer?

That is odd. Have you mentioned to your surgeon or nurse. Warmth usually indicates infection which you want to get checked out ASAP

If you can't go to mexico then go and see your PCP. If the port is infected it can be serious. The infection can run all the way along the tubing to the band and cause all sorts of issues. Your PCP should be able to do bloods to see if you do have an infection and if that comes back positive then you will need to decide if you should go back to Mexico or find a local bariatric surgeon.
