Hi. My girlfriend is normaly Ibuprufen tolerant. However when she is close to her period, if she takes this medication she can sometimes have severe stomach pains. Today she is within 2 or 3 days of starting her period and has pains in her lower back similar to if she has a trapped nerve or has pulled a muscle. She has taken 400mg of Ibroprufen and now has bad stomach pains. Why could this be?
