Burning sensation feeling on skin over pelvic area. no other symptoms. is this nerve damage or just caused from health anxiety and stress?ovarian cyst

It depends: The pelvic area is from navel to upper thighs. Are you saying lower abdomen or lower back/sacral area; deep or on the skin? Contact dermatitis may be one cause due to detergent or fabric softener in your panties or some other chemicals in that area. If it is not painful to press on lower belly, move the hips or lower back, bend or extend, then not likely internal or spine/joint related.
