Update: The home nurse service sent an RN to my house a few days ago. She told me that I can expect a bit of discomfort for a couple months. She said that the stoma site will probably first close on the outside and then seal up inside my abdomen.
One embarrassing development was when air or gas started escaping from the stoma and making a Whoopie Cushion sound, but the RN told me this is just a sign of normal digestion.
I am trying to consume more protein because the LVN told us that would help with the regrowth of tissue at the stoma site.
I went to my primary care doctor's office and saw a PA for a follow-up. He noted that there is still some fluid discharge that could indicate the infection near the stoma is still active so he prescribed Keflex. I had been taking Bactrim.
I have had no significant pain for the past couple days.
