Red light therapy for long covid?

I don’t know about Red Light Therapy, but I’ve been having Green Violet Laser Light Therapy and Red Violet Laser Light Therapy through my Chiropractor’s office here in Geneva, Il. I know that Red Light Therapy is different than the Red Violet Laser Light Therapy. I’ve noticed a slight increase in my ability to smell certain things ( I haven’t been able to taste or smell for 3 years today, the 14th of December). Covid or the vaccine did this to me! I also have a Covid tongue with lesions on it and they are going away! It costs me $20.00 for a 20 minute session. I’ve been doing this for about a month now and will continue to do so until I feel like it’s no longer benefiting me. I also feel a little more calm from having this Violet Light Therapy. Be sure it’s Green or Red Violet Light Therapy, as these light therapies are not the same.
