Botox vs. painkiller: which eases muscle pain better?
NCT ID NCT06899438
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study tested whether botulinum toxin type-A injections relieve pain from myofascial pain syndrome better than a standard local anesthetic (prilocaine). Thirty-eight adults with long-term muscle pain were randomly assigned to receive either botulinum toxin or prilocaine injections into their trigger points. Pain levels were measured before treatment and at 2 and 6 weeks after using standard pain scales.
