There are other names for laser treatments-
low level laser therapy (LLLT)
soft laser
cold laser

Sometimes LED light therapy can be confused with the true laser light therapy.. but usually LED would take longer time sessions.

Hmm, I wonder if since it worked for a short time it might take more than a few sessions to see lasting improvement..
but since your pain has increased... I can see that you'd be hesitant to try more..

Is the pain in the same area as before the laser?

Sometimes treatments will work for some , but not work for others.. very sorry your pain has increased..
