Hi, Welcome to Health care magic forum.
As you describe, it may not be a psychological pain. It depends upon the system she is facing problem.
If she has problem in sex, pain during period,pain during sex,it may be pelvic infection
, urinary tract infection
If there is problem with the bowel movements, frequency, or mucous in the stools, it may be due to the change in the diet, or infection of the bowels.
The other causes may be worms in the intestines, peptic ulcer
Wishing for a quick and complete recovery. Thank you.
