Lower back pain during menstruation is very common, and for many, it feels like a deep, dull ache in the lower back that can radiate into the buttocks or thighs. Although it is often related to normal bodily processes, it can still affect sleep, work, and mood. Here are practical tips on what you can do right now, and when it makes sense to have it assessed by a doctor.
Lower back pain during menstruation - typical causes
Many experience lower back pain during menstruation because the body releases prostaglandins, which cause the uterus to contract. These same signals can also contribute to muscles around the pelvis and lower back tensing up more, which can be felt as pain in the back.
Additionally, you may experience more tenderness in connective tissue and joints around the pelvis in the days leading up to bleeding, which can make you more sensitive to strain from sedentary work, lifting, or poor sleeping positions.
Lower back pain before menstruation - why it can start early
If you experience lower back pain before menstruation, it is often because the body is already undergoing hormonal shifts and preparing for bleeding. For some, symptoms gradually begin in the days leading up to menstruation and peak on the first 1-2 days.
Practical tip: track the pattern
Try to note for 2-3 cycles:
- When the lower back pain starts
- How long it lasts
- What provides relief (heat, movement, rest)
This makes it easier to plan relief in advance and provides your doctor with better information if you need an assessment.
Relief of lower back pain during menstruation - what you can try at home
The goal is often to reduce tension, increase blood flow, and find positions that provide relief.
Heat, movement, and breaks
- Heat on the lower back (heating pad or warm bath) can feel soothing for many.
- Gentle movement such as walks, slow hip circles, or gentle stretches can reduce stiffness.
- Change positions often, especially if you sit a lot. A cushion in the lower back can provide support.
Painkillers with caution
Some use over-the-counter medication for menstrual pain. Always follow the instructions on the package, and contact your doctor or pharmacist if you are in doubt, have stomach ulcers, are pregnant, or are taking other medication.
Exercises and positions when you have lower back pain during menstruation
You don't need a long program. 5-10 minutes can be enough if you do it gently and without forcing pain.
Three gentle suggestions
- Knees to chest (one at a time) at a slow pace
- Lying rotation: knees to one side, shoulders on the floor
- Pelvic tilt on your back: small movements, focus on relaxation
Stop if the pain significantly worsens, or if you experience new symptoms such as numbness, weakness, or sharp pangs.
When should you see a doctor for lower back pain and menstruation?
It is a good idea to contact a doctor if:
- the pain suddenly changes character or becomes very severe
- you have fever, dizziness, or are generally unwell
- you have very heavy bleeding or bleed between periods
- the pain affects your daily life month after month, or does not follow a recognizable pattern
For persistent or very severe pain, the doctor can assess whether other causes should be investigated, such as endometriosis or musculoskeletal issues.
Relevant products for support and comfort (if you are also pregnant or have recently given birth)
If your lower back pain is related to pregnancy or the postpartum period, support around the abdomen and lower back can make daily life more comfortable. A supportive belt can relieve back and pelvic discomfort, for example, the Maternity Support Belt.
In the postpartum period, some may also benefit from gentle support around the core, for example, the Post Birth Belly Binder.
