Back pain home remedies: the ice pack, the heat, and the order that matters

Almost everyone gets it eventually. You bend down to pick something up, or you sit badly for a week, or the stress of a bad month settles between your shoulder blades, and suddenly the simplest movements have to be negotiated.

French grandmothers treated a sore back in a particular order, and the order is most of the method: cold first, heat later, and movement throughout. Get those three right and the rest is comfort.

Here is how they did it.

Cold or heat: the 48 hour rule

This is the question everyone asks, and the answer depends on how old the pain is.

In the first 48 hours, use cold

After a wrong movement, a lift, or a fall, cold is what you want. Wrap ice cubes or a bag of frozen vegetables in a thin clean towel and hold it against the sore area for 10 to 15 minutes, up to three times a day.

Never put ice straight onto skin, and never leave it on longer than 15 minutes at a stretch. The towel is not a formality.

After 48 hours, switch to heat

Once the first two days have passed, heat is more comfortable and easier to tolerate. A hot water bottle at roughly 105 to 115 degrees Fahrenheit, never scalding, or a cherry pit cushion warmed through, held against the sore muscles for 15 to 20 minutes.

Keep a thin cloth between the heat source and your skin here too. A heating pad left on bare skin for an hour is how people give themselves a low temperature burn without noticing, and it happens most often to those who fall asleep on one.

Do not use heat on a fresh injury and do not use either on skin that is broken or that has lost sensation.

The Epsom salt bath

Epsom salt is magnesium sulfate, and a long warm bath in it is one of the oldest ways of persuading a knotted back to let go.

Fill the tub with warm water, around 99 degrees Fahrenheit, dissolve about 2 cups of Epsom salt, and stay in for twenty minutes with the water up to your shoulders. Dry off without rinsing.

Two or three times a week is plenty, and drink a large glass of water afterwards. Skip the bath entirely if you have heart trouble, kidney trouble or uncontrolled high blood pressure, and ask your doctor first if you are pregnant.

Whether the magnesium itself does anything through the skin is genuinely unsettled. The warm water and twenty quiet minutes are doing real work either way, and we would rather say that than dress it up.

Keep moving, and do not go to bed

This is the part that has changed most since our grandmothers’ day, and it changed in their favor.

Lying still for days makes ordinary back pain last longer. Gentle walking, getting up every half hour if you work sitting down, and normal daily movement are what get most sore backs back to normal. Rest when the pain demands it, then move again. If the muscle locks rather than aches, that is a different problem with a different answer: see muscle cramps.

Nothing on this page beats that, including everything below it.

A massage with wintergreen oil

Wintergreen contains methyl salicylate, which is chemically close to aspirin, and French households used it on stiff backs for exactly that reason.

Mix 2 drops of wintergreen essential oil into a teaspoon of a carrier oil, arnica or olive, and massage it into the sore area in slow circles until it is absorbed. Two or three times a day, for no more than a week.

Wintergreen deserves genuine caution. Not in pregnancy, not while breastfeeding, not on children under 12, not if you take blood thinners, and not if you react badly to aspirin. The National Center for Complementary and Integrative Health notes that essential oils are concentrated products and that swallowing them can be poisonous. This one goes on the skin, diluted, and nowhere else.

If any of those cautions apply to you, plain arnica oil on its own is a reasonable substitute, and so is a simple warm massage with no oil at all.

Golden milk, for the evening

A cup of warm milk with turmeric is an Indian tradition that French kitchens adopted long ago, usually at the end of the day.

Warm about 1 cup of milk or plant milk without boiling it, then stir in a teaspoon of ground turmeric, a pinch of black pepper, a teaspoon of coconut or olive oil, and honey to taste. The pepper is not optional if you want the turmeric to be absorbed at all.

Avoid it if you take blood thinners or have gallstones. NCCIH is clear that turmeric taken in ordinary food amounts is generally safe, and equally clear that the evidence for it as a treatment is not there yet. Drink it because it is warm and comforting at the end of a painful day, not because it is a medicine.

A green clay poultice

Green clay is one of those French remedies that survives because it is cheap and it feels good.

Mix green clay powder with a little cool water until you have a thick paste, spread it about half an inch thick on a cotton cloth, and apply the cloth to the sore area for one to two hours. Rinse with warm water afterwards.

Use a wooden or plastic spoon rather than metal, which is how it has always been done. Apply it cool for a recent strain and lukewarm for an old ache, which puts you back on the cold and heat rule from the top of this page.

The habits that prevent more back pain than any remedy cures

• Get up every half hour if you work sitting down. A short walk to the kitchen counts.
• Lift with your legs, load close to the body, and turn your feet rather than twisting your spine.
• Sleep on your side with a pillow between your knees, or on your back with one under your knees. A back that keeps you awake makes the next day worse, and what helps insomnia applies here too.
• Carry weight on both sides. A heavy bag on one shoulder every day does quiet damage over years.
• Deal with the stress. A back that hurts on Sunday evening and eases on vacation is telling you something, and what helps stress will help it more than any oil.

When to see a doctor

Most back pain settles within a few weeks with the measures above. Some does not, and a few kinds should never wait.

Go to an emergency room, or call 911, if you have:

• numbness in the groin or the area you would sit on
• loss of control of your bladder or bowels
• sudden weakness in one or both legs
• back pain after a serious fall or a car accident

Those can point to pressure on the nerves at the base of the spine, and that is measured in hours, not days.

Make an appointment with a doctor if:

• the pain has not improved at all after two to three weeks
• it wakes you at night or is clearly worse lying down
• it comes with fever, unexplained weight loss, or a history of cancer
• pain runs down one leg past the knee
• you are over 50 and this is the first back pain of your life

The real risk with a home remedy is rarely the remedy. It is the time it takes up while something else goes unattended.

FAQ

Should I put ice or heat on my back?

Ice for the first 48 hours after the pain starts, heat after that. If you are unsure how old the pain is, ice is the safer of the two, and cold on a chronic ache is uncomfortable rather than harmful.

Is bed rest good for a bad back?

No, and this is the clearest reversal of old advice on this page. Staying in bed for more than a day or two makes ordinary back pain last longer. Move gently, and rest only as much as the pain genuinely requires.

Can I use wintergreen oil if I take aspirin?

Do not. Wintergreen contains methyl salicylate, which is closely related to aspirin, and the two together are not a combination to improvise at home. Ask a pharmacist, who can answer this in a minute.
