bought this after i got a terrible sprained ankle at the beginning of may and it drastically helped with my recovery. every time i was in bed and wasn’t icing, i would use the red light patch. helped a ton with pain relief. sometimes after a long day my ankle will still ache and i’ll just do 20-30 mins with the red light and feel so much better. not overnight results, but with consistent use, makes such a difference.
the plastic cover tends to slip off, but it’s not a big deal to me considering i just wrap the patch around my ankle.
