Ankur --

In the search box in the upper right of each message-board page, type photodynamic (one word, not two) and hit the Go button. You'll get two pages of results, including three substantial threads.

The second and third threads were started by someone who has had PDT. You could send her an e-mail or a private message for additional details.

And here's another thread started by someone else who had the treatment.

All the best,
Leslie
