Welcome to the Healing Well Wrapped Club! Sorry to hear about your problems. Can I ask you about your surgeon? Did he/she have a lot of experience doing Nissens? It sounds as if you've had way too many problems to assume that the wrap was done correctly.
My first suggestion is to get yourself to another surgeon--one who is highly experienced in the Nissen procedure, and specifically, an expert in doing redos. Even if they can sort things out without having surgery again, you need to see someone who can get you straightened around, and it sounds as if that person is NOT the surgeon who did your Nissen.
What testing did you get before your surgery? Generally, these tests are standard: barium swallow, endoscopy, manometry, 24hr PH monitor (either wired or a BRAVO capsule), and often a stomach emptying test.
If you had the procedure this past March, you are still in the thick of healing. This surgery takes six months for the majority of healing and a year for the rest. It's not uncommon to have problems and discomforts in the first six months, but it sounds as if yours are extreme.
I'm sure others will be by soon to share their experiences and advice. You can get a lot of support here as you work through your problems.
Glad you've joined the forum. It's a good place to be. Hang in there!
