I have blood sometimes from incision site which is outside my rectum. For you it might be coming from incision site only not from fissure. I have not seen any blood in stool so far other than that when I wipe. I have sitting pain but very minimal (1.5 on scale of 10). I can actually sit and stand for long time. My only concerns right now is incision is not healed yet and slight leakage while passing gas. So far I am able to control my stool and gas.
I have been taking full meal right from day 1. It is actually recommended. Metamucil helped in bulky stool which I feel helped me reduce my BM to 1 per day. I have already started tough foods also like nuts and other things. so far they have not given any problem to me. My tips based on my experience.
1. Do not take stool softener instead take fibre supplement to make your stool bulky and help sprinter to adjust.
2. Incision site is outside of your rectum therefore leakage sometimes come from there and not from rectum.
