How to choose a joint pain gel without wasting another £30
Most people in this category have three or four half-used tubes in a cupboard. These are the five checks I use in clinic to avoid adding a fifth.
1. Read the carrier before the actives
The front of the pack sells you ingredients; the back tells you whether they can go anywhere. Arnica and MSM in a heavy petrolatum cream is a different product from the same actives in a penetration-focused gel. If the base is not designed to move things through skin, the actives stay in the top layer where the nerve endings are.
2. Separate sensation from mechanism
Menthol, camphor and capsaicin create a strong feeling and no anti-inflammatory action. That is useful for twenty to forty minutes after activity and useless for changing your mornings. Ask what the product does once you can no longer feel it.
3. Check concentration and standardisation
Look for named, standardised extracts and stated percentages. 'Herbal complex' with no figures is a marketing phrase. For drugs, the percentage is on the box — 1% diclofenac means something specific and testable.
4. Count the daily routine burden
A product that needs four measured applications a day will be used twice, and half-used products do not work. Twice-daily routines survive real life. Be honest about which one you will actually keep to for three months.
5. Apply the fortnight rule
Give anything credible fourteen days of consistent, twice-daily use before judging it, then judge it on duration of morning stiffness rather than on how it feels while you rub it in. Real effects accumulate; sensations do not. If nothing has changed by day fourteen, stop and try something else.
What a topical can and cannot do
No gel rebuilds cartilage. What a good one can do is reduce local inflammation and pain enough to change your day: shorter morning stiffness, stairs without planning, a night without waking. Movement, strength work and weight management remain the interventions with the strongest evidence in knee osteoarthritis, and a topical is a tool alongside them.
