Baking soda boost: could a kitchen staple improve pain injections?
NCT ID NCT07572994
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding sodium bicarbonate (baking soda) to a standard lidocaine injection can provide better pain relief for people with myofascial pain syndrome, a condition causing muscle pain and trigger points. Thirty adults will be randomly assigned to receive either lidocaine alone or lidocaine mixed with sodium bicarbonate. Pain levels and muscle activity will be measured before and after the injection to see if the combination works better.
