Hi Lou,Welcome to Healing Well! Sorry it took so long for you to get a response to your post! We try to get to all new members, but sometimes people fall through the cracks. My apologies!
I had the Nissen surgery nearly five years ago, in February 2009. I can tell you that once the surgical healing is complete, you won't have a bit of trouble walking. I'm a fitness walker (61) and love hiking over hill and dale. I do this with enthusiasm, and walk very fast. The Nissen has done nothing but improve my fitness, as reflux was affecting my lungs very badly before surgery.
Yes, you do need to get the testing. Otherwise, you might get the surgery for no reason! It is always horrible to be off the PPIs for that week before the PH test, but it's a necessary evil, and you'll make it through. For most of that time you can take Ranitidine (Zantac) and Maalox/antacids. There is a period close to the day of the test when you're off everything. Many of us have made it through the horror (really it's doable...not fun, but worth it in the end) and lived to tell about it.
As far as swallowing issues (motility), there are versions of the Nissen (partial wraps) that work well as far as reducing reflux, but allowing swallowing to occur, even with problem swallowers. Several who post/posted here have had great results with partial wraps.
So, go for those test, and get the surgery if you're deemed a good candidate. It can greatly improve your quality of life. The recovery is not easy. The first couple of weeks are especially challenging, but if you're prepared and have a good attitude, you'll do just fine.
It takes six months for most of the healing and a year for the rest. You will gradually improve over this time, so it's not all that difficult once you get past the early stages. As Bill, another moderator here, says, "It's a marathon, not a sprint!" Here's a link to my early recovery journal. It'll give you an idea about what the recovery looks like:
