Soft-tissue injuries — strains affecting muscles or tendons, and sprains affecting ligaments — are among the most common reasons patients visit a community pharmacy before or instead of an A&E department. According to NHS data, sprains and strains account for a substantial proportion of minor injury presentations across England each year. Pharmacists are well placed to provide first-line management, appropriate product selection and clear referral advice.

Strains vs Sprains: What Is the Difference?

Understanding the distinction helps pharmacists assess severity and advise appropriately:

Both present with pain, swelling and reduced range of movement. Sprains may also produce bruising around the joint. The severity spectrum runs from mild (microscopic fibre tears, full function retained) through moderate (partial tear, significant pain and swelling) to severe (complete rupture, inability to bear weight or use the joint).

The PRICE Protocol

The established first-aid approach for acute soft-tissue injuries is PRICE:

Protection — avoid activities that aggravate the injury. This does not mean complete immobilisation, which can delay recovery. Gentle movement within pain limits is encouraged after the first 48–72 hours.

Rest — reduce load on the injured area for the first 48 hours. Use crutches for lower limb injuries if weight-bearing is painful.

Ice — apply a cold pack wrapped in a cloth for 15–20 minutes every two to three hours during the first 48 hours. Never apply ice directly to skin. Frozen peas in a tea towel remain a practical pharmacy recommendation.

Compression — an elastic bandage or compression support can reduce swelling. It should be firm but not tight enough to restrict blood flow. Advise patients to check for numbness, tingling or colour change below the bandage.

Elevation — raise the injured limb above heart level when resting to help reduce swelling via gravity-assisted drainage.

OTC Pain Relief

Oral analgesics

Ibuprofen is the first-choice OTC analgesic for soft-tissue injuries, providing both anti-inflammatory and pain-relieving effects. The standard adult dose is 400mg three times daily with food.

NICE CKS advises avoiding NSAIDs in the first 48 hours after acute muscle injury if there is significant swelling, as the inflammatory response plays a role in early tissue repair. In practice, many patients present after this window. For the first 48 hours, paracetamol 1g up to four times daily is an appropriate alternative.

For moderate to severe pain, combining paracetamol and ibuprofen at their standard doses is safe and more effective than either alone, as they work by different mechanisms.

Topical NSAIDs

Topical ibuprofen gel (5% or 10%) and topical diclofenac gel are effective for superficial musculoskeletal pain. They achieve therapeutic concentrations in underlying tissue while minimising systemic exposure and gastrointestinal risk.

Advise patients to apply a 4–10cm strip (depending on the area) and massage gently into the affected area three to four times daily. Topical NSAIDs are particularly appropriate for patients who cannot take oral NSAIDs due to gastrointestinal, renal or cardiovascular risk factors.

Heat vs cold

The timing matters:

• First 48–72 hours: cold therapy (ice packs) to reduce swelling and numb pain
• After 72 hours: heat therapy (wheat bags, hot water bottles) to relax muscles and promote blood flow to the healing area

Some patients find alternating heat and cold helpful for persistent stiffness. There is no strong evidence favouring one protocol over another after the acute phase.

Supports and Braces

Elastic compression supports (ankle, knee, wrist) are widely available in pharmacy and can provide stability and reassurance during recovery. They should be used during activity rather than continuously, as prolonged immobilisation weakens surrounding muscles.

Tubigrip-style tubular bandages are also effective for compression and can be cut to size for different limb circumferences.

When to Refer

Pharmacists should advise medical assessment (GP, minor injuries unit, or A&E depending on severity) if:

• The patient cannot bear weight on the injured limb
• There is significant deformity suggesting fracture or dislocation
• The joint is locked or gives way
• Swelling is severe, rapid or does not reduce after 48 hours of PRICE
• There is numbness or loss of circulation below the injury
• Pain is disproportionate to the apparent injury mechanism
• The injury occurred during a high-energy impact (e.g. road traffic collision, fall from height)
• Symptoms have not improved after two weeks of self-management

Ankle injuries in particular can mask fractures. The Ottawa ankle rules — used in emergency departments to determine the need for X-ray — suggest that if the patient can bear weight and take four steps immediately after the injury and in the pharmacy, a fracture is unlikely. However, this does not replace clinical assessment.

Recovery Expectations

Setting realistic timescales helps patients manage their recovery:

Pharmacists should advise gradual return to activity — not "rest until it stops hurting, then return to full activity", which is the most common cause of re-injury.
