Hi, Steve - and welcome.
I'm sorry to learn that you're not doing too well at eight months post-op. Some AN surgery patients do have ongoing problems post-op but they usually resolve with time and/or some form of therapy. Fatigue is common to all post-surgical AN patients. I certainly experienced it and even today, just about 4 years out of surgery, I still don't have the stamina I used to. I attribute some of that to my age (67) but I believe that it's partially due to the trauma the surgery imposed on my aging but otherwise healthy body. That having been stated, some of our members are extremely physically active following surgery. I'm talking about running marathons, long-distance biking, etc. These folks are usually younger and had an excellent surgical outcome. Sometimes, it takes time to regain complete wellness - but it does come, as some of the posts you may read on these forums, prove.
Because I'm not a doctor and don't have much information about the size of your AN and what your doctor has stated to you regarding your recovery issues, I'm going to suggest that he would be the first person to talk to about your recovery issues, based on his medical knowledge and familiarity with your case. I also realize that some doctors lose interest in their surgical patients once the operation has been successfully completed. That is unfortunate and I hope it isn't the case for you.
Of course, as AN patients we can empathize with your frustrations. I hope we can offer you some practical advice as you struggle with your post-op issues. Collectively, our members have a wealth of practical knowledge that may be useful to you and we'll be here to support you in whatever way we can. Please consider these forums as a resource. We want to help.
Jim
