Laser Hair Removal and Stomach Nausea?

I started getting laser hair removal in April this past year on my stomach. Around that time, I started becoming severely nauseated. I have had sonograms, X-rays, blood work, I have been tested for gluten allergies, changed my eating habits, been on all natural supplements, had lower GI panels done, you name it I have been checked for it. No Drs have mentioned anxiety because I don't display other symptoms. The nausea usually starts around the time of my treatments. Anyway this is linked?
