For the better brands and a decent size for coverage, yes.

You might also look into near/far infrared (aka FIR) / jade mats if you have whole body pain/symptoms.

Laser would be difficult to do for mostly whole body issues, but the FIR and jade type mats or lights might work better in those cases.
A little more outside the mainstream but who knows maybe it will help.

Ask about a trial time or returns if no results etc.
