Every month I experience very painful periods and heavy bleeding. It is so painful that I miss my classes one-two days a month and I cannot do anything during that time. Also, my clitoris is very insensitive to physical stimulation. I take thyroxine 75 mg daily in the morning. I was diagnosed with hypothyroidism at age 9 or 10( I had Cholesterol 330mg/dl at that age). My thyroid functions normally now (I have consulted endocrinologist) and I am not obese. I was also treated for osteomyelitis in my right arm when I was 4 months old. This is my medical history and I would like to know whether the period pain and the insensitive clitoris is normal or are they an indication of something else.
