Feeling like something is stuck inside my is there with me even more also. An outcome of some heat at surgical site as round heals, some discharge and swelling. It will subside gradually.
Having BMs like once a day even if you feel you have not fully emptied is ok.
If you still have doubts then visit a doc. If your original doc doesn’t listen then go to another one and explain your symptoms and ask them is that ok and else suggest what to be done.
