im not sure what my PT called it but they treated my spine injuries with some kind of light therapy and it helped but when I started with RSD no not so much...then they tried icy hot...(DO NOT DO THAT ON RSD). other than that. if not for RSD i suggest you make mention of it . it was minor relief but solid science as it helps repair some damage.. my neck was healing (BR) thats before RSD. now ..not so much.and since you are an Islander I Know a lot of PT places use it..
