My port site was sore to the touch for about the first 9 months. It was a constant pain for the first 6. After about 9 months the pain went away all together though. I would consider calling your Dr for the best information.
Your fills depend on the type of band you have. My band can only tolerate 5cc's per fill at one fill per month. Some bands can take more and some take less. You eventually can fill your band to the max level for your type but that can cause esophogal corrosion and disease. If the band is too tight nothing can pass through.
Dr. Muse does fills for $260. I had my surgery done in Mexico, as have other patients of his. His is super nice and reasonably priced. Definitely look him up. He's at Advanced Medical Weight Loss on Highland Dr in Salt Lake City. 801-272-4111
