I have stomach bloating with altered bowels and low grade fever. Can diverticulitis cause this?

Hello doctor,

I was diagnosed with diverticulitis from a CT in February. They gave me antibiotics and for the first time in months, I finally felt good again. Exactly one month later it happened again, and they called me in another round. For years the primary has told me it was just IBS. But I have had about of diarrhea/constipation (at the same time) every month since fall. Each time I run a slight fever 99.6 fahrenheit for about two days if I stop eating and it usually improves. I can never figure out what is safe to eat. My skin is looking much older now, and I never feel good. I also stay somewhat anemic.

Two and a half weeks ago, I had my left kidney removed due to cancer. The results were good and no treatments needed, and my incisions are healing well. But instead of being elated about that, I am having the same bloating, lower mostly left belly pain, and what seems like I cannot empty my bowels. I go often, but it looks like dust in the bowl and it is very little. So today I am back on liquids and have a fever of 99.6 fahrenheit. Mine often is at 97.6 fahrenheit. I have some numbness and pain in that same area from the surgery. It is like nerves, it prickly and it burns. It goes from my left groin on that side of my pelvic area and only a couple inches upward. The first week I had no feeling there.

The surgeon says it usually takes about six weeks for that to improve. He has me on stool softeners because it takes a while to get things working right again. What I need to know is, could this be diverticulitis every time this happens? Just would like a solid opinion and any advice on how I could make this better at home.
