I have had low level laser therapy about 4 times beginning March of 17 (12 sessions), June 17 (4 sessions), September 17 (6 sessions) and January of 19 (4 sessions). It helped me quite noticeably the first session. After that it was maintenance to keep the neuropathy in my feet and not let it start traveling up my ankles and lower legs. It seems that about 3 times per year of 4 to 6 sessions work for me. My neuropathy now consists of numbness in the bottom of my feet and a tenderness in the top of my feet that requires only the most comfortable and loose shoes.
