This site is not necessarily a good place to give directions, as contact information sometimes has resulted in programs being shut down. One place has decided only to accept phone calls. But there is no program that I know of in Boston yet.
Things are likely better in Italy, but there is a large trial going on in Buffalo New York and most other places are still waiting for Institutional Review Boards.
There are a few lists of places to get testing and treatment, but shutdowns happen all the time so these lists easily go out of date. I realize reading through this whole site is impossible for a 8.5 who has only English as a second language, but you may be able to get better information by sending a PM to someone from one of the sticky topics.
