Can your monthly cycle cause other pain like in your knees?

Possibly: There is some debate if a women's menstrual cycle can cause joint pain particularly in the knees. The other issue is that many rheumatic diseases such as Rheumatoid or Lupus can worsen during menses. I would say if the pain only occurs during your cycle try some over the counter anti-inflammatories. If the pain spreads to other joints or lasts longer then your cycle, seek medical attention.
