PMS, or premenstrual syndrome, is a common phenomenon: roughly 15 out of every 20 women who menstruate experience at least some of the manysigns of it, per the National Library of Medicine. So you're not alone if, among other things, your breasts hurt, your head hurts, you feel extra emotional, or your stomach feels like it's revolting against you in the seven to 10 days leading up to your "special time."
For the majority of women, PMS symptoms are minor. In fact, some women report feeling their best and most clearheaded during the premenstrual phase of their cycles. But for others, PMS is frustrating, and for still others, it's severe enough to interfere with activities.
While experts think cycling hormones probably have something to do with PMS, they're not sure exactly what's behind it. For example, studies show that women who experience it don't necessarily have abnormal levels of hormones. "We don’t really know what causes PMS as a general thing, so all of the theories are just that — they’re theories,"Raquel B. Dardik, MD, clinical associate professor, Department of Obstetrics and Gynecology at NYU Langone’s Joan H. Tisch Center for Women’s Health, tells Refinery29. Various other factors, like stress levels, other medical conditions, even cultural influences seem to play a role. Women born into Western cultures like the U.S. tend to experience more mood swings, for example, suggesting that there's something specific to our pressures at play.
You should never hesitate to talk to a doctor if your periods have recently become especially severe or suddenly irregular. Hiccups happen, but major shifts can be a sign of a medical issue like a pregnancy, an infection, or something else. Dr. Dardik explains that "the most important thing is for people to actually track their symptoms along with their cycle." Doing so will help you differentiate something that is premenstrual syndrome [from] something that’s a lot more chronic and should be evaluated."
But if you're wondering how to ride out those less troublesome, but still nagging, PMS symptoms, look no further. Here are some tips for solving symptoms, and more info on why they're happening to you in the first place.
Cramps
Fun fact: Medically speaking, cramps are *technically* not a symptom of PMS. "Most people have cramps immediately before their period," Dr. Dardik explains. But splitting hairs here can get a little tricky: "People who have cramps tend to have other symptoms that are related to PMS, such as irritability and mood changes, so it’s hard to tell if that’s because you’re feeling crappy because you’re having cramps or because you have concurrent PMS."
Either way, we should talk about them because, let's face it, they really suck.
Doctors refer to them by the much more sinister-sounding term dysmenorrhea (doesn't that just sound evil), but the reality is there are plenty of treatments for menstrual cramps. Common pain relievers, like ibuprofen or naproxen, can help in the moment; take the lowest dose possible at the first twinge of pain to get ahead of it.
If your cramps are severe, your doctor might prescribe a hormonal birth control method like the pill or a hormonal IUD, either of which can help painful periods. For some women other methods, like exercise or having an orgasm, may help, though the science is unclear about how well those work.
Breast Pain
Breast pain goes hand in hand with menstruation thanks to hormonal changes in your body, though experts aren't totally sure why. Dr. Dardik suggests that it can also be related to "expansion — microscopic expansion — of the breast tissue." Your breasts may feel tender or swell to be noticeably larger, and this can start as early as two weeks before your period, around ovulation.
The technical term for this kind of breast pain is "cyclical mastalgia" and severity can vary widely. While some women feel only slight tenderness, others can barely wear a bra.
How bad it is will determine what course of treatment your doctor recommends. Common methods include avoiding caffeine, keeping your breasts supported with a well-fitted bra, and eating a low-fat diet. For more severe cases or those that don't seem to be getting better, medications are available.
Back & Joint Pain
Nebulous aches in your muscles or joints are also a relatively common PMS symptoms, as is the more specific symptom of low back pain.
"We’re not entirely clear why premenstrual changes would cause muscle pain," Dr. Dardik says. She goes on to explain that it can be due to a ripple effect, with pain that starts in your uterus moving out to your back: "Nerve endings are not pinpoints, so sometimes when one nerve ending is irritated, you feel pain in other places."
Low back pain, she says, can be due in part to this same effect, but it's "more common with women whose uteruses are retroverted because they’re facing backwards toward the back."
Either way, the best first response is a heating pad or hot water bottle.
Mood Swings
The idea that your period messes with your mood has been notoriously overblown. In fact, studies have yet to define a link between hormones and changes in mood.
However, Dr. Dardik says that premenstrual mood changes can still happen, and it's important to keep track of them. They should be consistent from month to month, and "if you’re having problems during your period or immediately after, that’s sort of a trigger that this isn’t PMS."
Also, somewhere between 5% and 10% of women do experience extreme premenstrual mood changes that could signal PMDD, or Premenstrual Dysphoric Disorder. If you're noticing more serious cyclical mood changes, like depression, anxiety, or serous irritability, talk to your doctor. It's estimated that 40% of women suffering PMDD may really be dealing with another mental health issue that's gone under the radar.
But don't freak out; the important thing to know about this is that these issues are treatable, and you don't have to put up with them.
Nausea
This can be another after effect of those cramps or the digestive issues that occur before and during your period.
There is sadly no sneaky way around it. Dr. Dardik says maintaining a healthy lifestyle — "get enough sleep, get enough exercise, don’t have too much sugar or too much caffeine"— is the best preventative measure against premenstrual nausea.
A hot water bottle may also come in handy, and, as with any kind of nausea, it's always good to err on the safe side and eat foods that are easy on the stomach— toast, rice, fish, and bananas.
