I had hysterectomy and had the same problem, I consulted my doctor at the time and he identified that it was common, my solution was to stay away from foods that had a lot dairy products also ate a lot of soups.
This is common problem after hysterectomy. The gases in stomach and constipation cause fullness in the stomach. This can be due to lack of walk or exercise. The recovery time after hysterectomy depends upon the type surgery. Usually it take six weeks for complete healing but some ladies recover after 3-4 months. For more details, visit hysterectomy.

I was told that it's constipation but it's almost six months so it's possible or impossible.I walked lots but it does killing my back pain on my left side all the times.stomach is still very tender. I was told that there is nothing to related to the surgery about my back
