Thank you, Mypoorbutt and Chachacha,
Your encouragement and advice from experience mean a lot to me. I am trying to be patient, but the pain is wearing me down, to be honest.
Today has been the same as yesterday, with a few differences. I slept more last night, so that is good. The pain is a bit different today. There is heaviness/soreness/achey type of pain on the anterior part, which is better when I lay down on my stomach and worse as I stand up or lay in any other position. I am trying to walk a little around the dining table, but I am managing only a few minutes at a time, before the heavy/soreness pain gets too much and I have to get back to the lying on my stomach position. There are also random short twinges of pain in random locations around the anus, that feel like a needle stab. These are not often, less than 10 times today.
Today I had a BM, it was soft (Bristol 3/4), due to Colace (50mg) and Milk of Magnesia (1TBSP) (with which I am trying to counteract the oxycodone, and my stools are normally hard, Bristol 1/2 (the opposite problem from you, Mypoorbutt)) and I did not feel that all of it came out. The pain was intense, and it gave me a new fissure - a small one that I can clearly see bleeding. The other 3 fissures that I had prior to surgery are open as well and have not healed, but they were not actively bleeding, which is good because they bled with almost every BM for about 3 weeks prior to surgery. All I can do is cry at this point, both from the pain and the disappointment. I don't know why I thought that the poop would just fall out without problems, after a LIS... somebody must have written that and I was dreaming of it.

For pain, I've taken acetaminophen325mg+oxycodone5mg every 4-5 hours and I also apply Lidocaine ointment prior to BM. With this, the pain is cut about in half.
