Had Hysterectomy, Followed By Fluid Leaking From Lymph Nodes With Blood. Have Pain While Passing Stool. Suggest?

I had a full blown hysterectomy mid July. About 2 weeks later I started leaking fluid from my lymph nodes (i had gone back to the hospital to find out about my leaking and that is what they said it was). I've started to add blood to this leak because I can smell it, Now it's getting to the point I can see discoloration, When I go poo, OMG! The pain! The pain takes my breathe away and has made me want to throw up! It doesn't matter if it's gas, runny stools, hard stools, it's the contraction of the muscles that push the poo out that hurts so bad. I don't eat because I know it's going to have to come out the hurting end. When I first got home, I had no problems with pain when I pooped. It's getting worse as time goes on.
