Back Pain and Muscle Strain Relief at Home: Heat or Cold, Pain Balms and When to See a Doctor

Quick answer: Most back pain and muscle strains are not serious and settle within 2 to 6 weeks. Keep moving, avoid bed rest, use cold for the first 48 hours after a strain and heat for stiff muscles, and take paracetamol or ibuprofen for a few days. Balms and sprays give short-term comfort only. See a doctor for leg weakness, numbness, bladder or bowel problems, fever, or pain after a fall.

Why does my back, neck or shoulder hurt?

Most back and neck pain comes from muscles, ligaments and small joints, not the bones or spinal cord. Common triggers in Bangladesh:

• Lifting a heavy load with a bent back, or a sudden twist.
• Sitting for hours at a desk, on a bus, or behind a sewing machine.
• Long days on a rickshaw or motorbike.
• Stress, poor sleep and weak back muscles.

A muscle strain means some muscle fibres are overstretched or torn. It hurts most for two or three days, then eases. A “slipped disc” (a disc between two spine bones pressing on a nerve) is much less common and usually causes pain shooting down one leg (sciatica), with tingling or numbness.

How long does back pain or a muscle strain last?

The NHS says back pain usually improves within a few weeks, and most strains feel better after about two weeks. Mayo Clinic says most back pain improves within a month with home care. Most people need no scan or injection.

What helps back pain and muscle strain at home?

1. Keep moving, do not rest in bed

This is the most important tip. The NHS and Mayo Clinic both advise staying active and avoiding long periods in bed. Lying still makes muscles stiff and weak. Walk a little every hour and keep doing your daily jobs gently. Some discomfort is normal.

2. Take posture breaks

If you sit for work, stand and move for two minutes every 30 to 45 minutes.

3. Heat or cold: which one?

Both help, at different times. The NHS advises an ice pack for pain and swelling, and a heat pack for stiffness or muscle spasm. Avoid heat in the first two days after a strain.

Situation	Use	How
First 48 hours after a strain, twist or fall	Cold	Ice pack in a towel, up to 20 minutes, every 2 to 3 hours
Stiff, tight or aching muscles; old back pain	Heat	Wrapped hot water bottle, 15 to 20 minutes
Not sure	Either	Use what feels better
Never	Heat over a balm or spray	Can burn the skin (see below)

Always keep a cloth between the pack and your skin.

4. Simple exercises

Start gently after two or three days. Sharp pain means stop.

1. Knee hugs: Lying on your back, pull one knee to your chest, hold 10 seconds, then the other. 5 times each.
2. Pelvic tilt: Lie with knees bent. Press your lower back into the floor, hold 5 seconds. 10 times.
3. Cat and cow: On hands and knees, slowly arch your back up, then let it sag. 10 times.
4. Neck turns: Slowly turn your head left and right, then ear to shoulder. Hold 5 seconds. 5 times.
5. Walk: 10 to 30 minutes daily.

Keep exercising after the pain goes; strong back muscles prevent the next episode.

5. Sleep and lifting

A medium-firm mattress suits most people. Sleep on your side with a pillow between your knees and one pillow under your head. When lifting, bend your knees, not your back, hold the load close, and do not twist.

Which painkiller should I take for back pain?

For a simple strain, paracetamol is a safe first choice for most adults: 500 mg to 1 g every 4 to 6 hours, maximum 4 g in 24 hours (3 g if you are small or have liver problems). Napa 500 mg is a common brand; see our article on paracetamol limits.

For low back pain, the NHS says paracetamol alone is often not enough. Ibuprofen may work better but is not for everyone. Take it with food, for a few days only. Avoid it with a stomach ulcer, kidney disease, heart failure, uncontrolled high blood pressure or pregnancy, and never for fever in dengue season.

Do pain balms and sprays like Moov actually work?

Balms, oils and sprays are “counterirritants”. Menthol, camphor, wintergreen oil (methyl salicylate), eucalyptus, turpentine and capsaicin make the skin feel cool or warm, which distracts the brain from the deeper ache. They do not repair the strained muscle. See MedEasy's Pain and Cold Relief section.

What the evidence says

• Good evidence: topical NSAID gels. A Cochrane review found diclofenac gel gave good pain relief in acute sprains and strains, with only mild skin effects. Diclofenac gels such as Voligel and Clofenac are listed under Diclofenac Sodium.
• Limited evidence: wintergreen and salicylate rubs. A Cochrane review found no good evidence that salicylate rubs give useful pain relief; larger, newer studies showed no effect.
• Limited evidence: menthol, eucalyptus, turpentine, clove and capsaicin rubs. Small trials only. They give short-term comfort to many people, but do not expect a cure.

How to use a balm or spray safely

Products under pain relief balms, oils and sprays include:

• Moov Spray 35 g: the pack lists wintergreen oil (methyl salicylate), mint, eucalyptus and turpentine oil. The pack says spray about three times a day, not on broken or inflamed skin, away from the eyes and face; ask a doctor in pregnancy. The pack gives no children's dose.
• Zandu Ultra Power Balm 8 ml: the pack lists menthol, wintergreen oil, clove oil and capsaicin extract. The pack says massage a small amount in 2 to 3 times a day, maximum 4, not on open wounds; for adults and children over 5.
• Moov Cream 100 g: the product page says only “natural ingredients” for muscle strain and joint pain, and to follow the label. Check the pack for ingredients.

Safety rules for all of them (FDA and NHS advice):

• Never apply heat over a balm or spray, and do not bandage the area tightly. The US FDA has reported serious burns from menthol and methyl salicylate products.
• Not on broken, irritated or sunburnt skin. Keep away from eyes, nose, mouth and private parts; wash your hands after use.
• Use a thin layer on a small area; large areas and frequent use increase methyl salicylate absorption. Avoid wintergreen products if you are allergic to aspirin, take warfarin or are pregnant, unless a doctor agrees.
• Camphor and menthol products are not for children under 2. Camphor is poisonous if swallowed; keep balms out of children's reach.
• Sprays are flammable. Stop if you get pain, blistering or a rash.

When should you see a doctor for back pain?

Call 999 or go to an emergency department now if you have:

• Weakness, numbness or tingling in both legs, or weakness that is getting worse.
• Numbness around the genitals or back passage.
• Difficulty passing urine, or loss of control of urine or stool.
• Pain after a serious accident or fall from height, or with chest pain.

See a doctor within a day or two if you have:

• Fever or feeling generally unwell.
• Pain that is severe, worsening fast, or worst at night.
• Unexplained weight loss.
• New pain after age 50, or a history of cancer, TB, osteoporosis or long-term steroid use.
• Pain after a fall in an older person.

Book a routine visit if the pain has not improved after about four weeks, or leg pain (sciatica) lasts beyond six weeks. You can talk to a licensed doctor online through MedEasy doctor consultation.

Common beliefs and questions in Bangladesh

“Bed rest cures back pain.”

No. This advice was reversed decades ago. Rest a day at most if the pain is very sharp, then start moving. Movement is the treatment.

“A diclofenac injection from the pharmacy is the quickest fix.”

No major guideline recommends routine painkiller injections for simple back pain. The drug is the same as the tablet or gel, but the needle adds injection-site damage and infection to the same kidney and stomach risks. Also avoid forceful “bone setting” by unqualified people; it can injure nerves.

“The stronger the burning of the balm, the better it works.”

No. The heat you feel is a skin sensation, not healing. The FDA found the worst burns came from high-strength menthol and methyl salicylate products. Use a thin layer; stop if it stings badly.

“Back pain always means a slipped disc or a kidney problem.”

Most back pain is muscular and settles on its own. A slipped disc usually causes leg pain and numbness; kidney pain usually comes with fever, burning urine or pain in the side.

“I must stop all exercise until the pain is 100 percent gone.”

No. Waiting for zero pain keeps you weak and stiff. Return to gentle activity early and build up slowly. Namaz postures, walking and housework are all good for your back once the sharp pain has eased.
