The HT that I had a few years back was performed in Allentown, Pennsylvania. Yes, the swelling was very bad. I was in alot of pain for over a week. The back of my head took almost a year before that tingling on the back and top of my head went back to normal. There are noticable blank spots where transplanted hairs were supposed to grow, but never did. Overall I was very disappointed with my experience. Some of the hair grew, but not nearly as much as was promised. I was in lots of pain and discomfort with tons of swelling for over a week. It wasn't supposed to be this painful, but it was.
