The director of the gynecological pain at NorthShore University Healthsystem, Frank Tu said that many doctors are taught that ibuprofen "should be good enough" to combat such pains.
Professor John Guilleaud from the University College London said menstrual cramping can be as "bad as having a heart attack".
Dysmenorrhea, the clinical term for painful periods, has no definitive medical origin.
The other main cause of menstrual pain is endometriosis where tissue normally lining the uterus is found on the pelvis, fallopian tubes or ovaries.
In addition to causing extremely painful menstrual cramps, untreated endometriosis can cause infertility.
The "million dollar question" is why some women suffer more from period pain than others, according to Dr Richard Legro from Penn State College of Medicine.
Professor John Guilleaud said: "I think it happens with both genders of doctor.
"On the one hand, men don’t suffer the pain and underestimate how much it is or can be in some women.
"But I think some women doctors can be a bit unsympathetic because either they don’t get it themselves or if they do get it they think, ‘Well I can live with it, so can my patient`."
