My surgery has had a lot of complications, some of them similar to what you describe. My SRS was all the way back at the end of 2009 & I am only now starting to come to terms with how it all turned out for me.
Although I had my surgery with Dr. McGinn - and I'm satisfied with how she did things - I had already had a history of an orchiectomy not done the right way, so Dr. McGinn did not have enough material to work with. So, for me, a significant part of the problem was caused by getting an orchi from someone who didn't know how to do that for a trans person. But then there was the granulation overgrowth, which I still don't understand why my body reacted the way it did.
The main issue with my surgery was granulation overgrowth - my skin was very sensitive to the procedure & essentially "overhealed" itself. There was so much granulation tissue that I was having problems with both urination & bowel movements. In response to the granulation, they used a liberal amount of silver nitrate on it - in fact, so much to the point where the silver nitrate actually ended up entering my urethral area and burning my urethral tissue, which resulted in a temporary inability to urinate (I had to go to the ER where they re-opened it).
Due to where I got my surgery & where I lived at the time, I ended up getting my aftercare from someone other than the surgeon. They too were shocked to see how much granulation tissue developed. Due to physical pain, my mental status at the time & the fact that there had not been a lot of skin to begin with (before surgery)- all of these resulted in me ending up with almost no depth. Part of this was because of how things went - part of it was because I ended up going through a major depressive episode (of my Bipolar disorder) and not being able to care for myself properly.
I can empathize with surgery not turning out well. I understand & I will listen. In terms of solutions, I found that I had to learn patience & how to practice radical acceptance. Which of course sounds simple & easy but are in fact hard, excruciating things. I'm still trying to find solutions, but for now, I can offer someone to talk to...
